1. Cleaning Up PDFs Before You Share Them

PDF files often grow larger than they need to be. They can contain unused images, blank pages, and old revisions that no longer matter. With the PDF tools in File Tools, you can merge several documents together, remove the pages you do not need, and export a smaller, cleaner file that is easier to email or upload.

A common workflow is to drag in a stack of PDFs, reorder pages visually, delete duplicates or blank pages, and then export a single compact document. Because the work is done in your browser, you can comfortably tidy up internal or sensitive documents without sending them to a third-party conversion service.

• Combine multiple statements, forms, or reports into one PDF.
• Strip out covers, terms, and instructions you do not need to forward.
• Export key pages as images for slides, chat apps, or documentation.

If a file refuses to process, it is usually encrypted, password-protected, or corrupted. In those cases, re-export the file from the original application or print it into a new PDF before trying again in File Tools.

2. Compressing Images for Email and Web Uploads

Modern cameras and phones produce very large images by default. That is great for printing, but it can make email attachments and form uploads painfully slow. The Image Converter and Image Compressor tools let you resize and re-encode those images directly in your browser, with a simple trade-off between quality and file size.

You can convert lossless PNG screenshots to smaller JPGs, downscale oversized photos before uploading them to a website, or convert older formats to modern WebP or AVIF where browsers support them. Batch processing makes it easy to adjust a whole folder of images at once and download optimized copies.

• Convert screenshots from PNG to JPG for smaller email attachments.
• Resize high-resolution images to fit online form limits.
• Experiment with different quality levels while keeping the original files untouched.

If an image looks too soft or washed out after compression, increase the quality slider slightly or keep a higher-fidelity version for archival use while sharing the compressed copy.

3. Working with ZIP, TAR, and 7z Archives in the Browser

Archives are still the easiest way to bundle many files together. Unfortunately, not every device has the right tools installed to preview a ZIP, TAR, or 7z file. The archive utilities in File Tools let you open and inspect archives directly in the tab, without installing another program.

You can drop an archive to see its file list, download only the item you care about, or re-package a subset of files into a new ZIP or TAR. This is especially helpful when you receive a very large archive but only need one spreadsheet, configuration file, or image from inside it.

• Peek inside unfamiliar archives without extracting everything.
• Grab one or two files instead of unpacking the entire archive.
• Rebuild archives in a format that your target system understands.

All of this runs in the browser using WebAssembly builds of LibArchive.js, which means the actual file contents never leave your device.

4. Checking DNS, SPF, and Email Deliverability

If users complain that email is going to spam or disappearing entirely, DNS records are often the root cause. The Network / DNS Toolkit in File Tools can query A, AAAA, MX, TXT, CNAME, NS, SRV, and CAA records over DNS-over-HTTPS using public resolvers such as Google and Cloudflare.

The SPF parser expands includes, counts DNS lookups, and highlights potentially problematic configurations. DMARC and related TXT records are displayed in a single view so you can quickly see whether a domain is configured to monitor, quarantine, or reject spoofed messages.

• Verify that MX and SPF records are present and correctly formatted.
• Inspect DMARC policies without logging into your registrar each time.
• Spot over-complicated SPF records that may hit lookup limits.

These tools are meant for quick checks, not full-blown monitoring, but they can save a lot of time when you are trying to understand why a particular domain behaves the way it does.

5. Parsing Logs and Splitting Huge Files

Application and web server logs grow quickly and are rarely small enough to open comfortably in a standard text editor. The Log Parser and File Splitter tools in File Tools are designed for these situations and run entirely in your browser.

You can feed Apache, Nginx, IIS, and similar logs into the Log Parser to summarize traffic by IP, endpoint, status code, user agent, and geographic location. If a file is too large to handle all at once, the File Splitter can chop it into smaller pieces by line count so you can open each part in your editor or spreadsheet of choice.

• Split million-line logs into many smaller files in a single step.
• Spot noisy IPs, failing endpoints, and sudden spikes in error codes.
• Export CSV summaries to share with teammates or import into BI tools.

Because everything happens locally, you can experiment freely with production logs without copying them to remote analysis services.

6. Creating True Direct-Link QR Codes

Many online QR generators point the code at a tracking or redirect service instead of your actual URL. The QR Code Generator in File Tools builds true QR codes that embed your exact link, Wi-Fi configuration, or short text without an extra hop in the middle.

You can generate QR codes for websites, email addresses, SMS messages, and small contact cards, then export them as PNG or SVG. All encoding and rendering happens locally so you keep control over what is actually encoded.

In general, browser-based tools shine when you need quick, focused conversions or diagnostics without installing extra software—merging a couple of PDFs, checking a DNS record, shrinking an image, or inspecting a log file. For always-on automation or massive batch processing you might still reach for dedicated desktop or server software, but for everyday tasks the browser is often the most convenient place to work.

1. Cleaning Up PDFs Before You Share Them

Large PDFs are a pain to email, upload, and store. Many documents include hidden images, unneeded pages, and metadata you do not actually care about. With the PDF tools in File Tools you can trim a document down to just what you need and export a lighter version that is easier to send.

A common workflow looks like this: you merge several PDFs into a single file, remove pages that are duplicated or blank, and then export only the pages you actually need. Because all of this runs inside your browser, you can work on internal or sensitive documents without sending them to a remote service.

• Combine multiple statements or reports into one PDF.
• Strip out cover pages or terms you do not need to forward.
• Export key pages as images for slide decks or chat apps.

If a PDF refuses to process, it is usually either encrypted, password-protected, or corrupted by another program. In those cases, re-export from the original application or print to a fresh PDF before trying again in your browser.

2. Compressing Images for Email and Web Uploads

Modern phones and cameras produce photos that are much larger than most websites or email systems expect. A single JPG can be several megabytes. If you are sending screenshots, design mockups, or product photos, it is usually safe to compress them before sharing.

The Image tools let you drag in PNG, JPG, or WebP files and export smaller versions without switching apps. You can reduce resolution, adjust quality, or convert between formats. Many people convert PNG screenshots to JPG for email and chat because they are significantly smaller while still readable.

• Convert lossless PNGs to JPG for faster sending.
• Resize high-resolution photos before uploading to forms.
• Batch-process multiple images in your browser, then download the optimized copies.

If an image looks washed out or blurry after compression, try a slightly higher quality level or keep the original for archival use and share the compressed version only when speed matters.

3. Working with ZIP/TAR Archives in the Browser

Archives are still the easiest way to bundle a folder of files for storage or delivery. When you receive a ZIP or TAR.GZ file, you may not have admin rights to install tools on the computer you are using. The Archive tools on this site let you inspect and extract those files entirely in the browser.

Drop an archive into the tool to see its contents. You can download individual files or repackage the entire archive as a new ZIP or TAR. This is especially useful when you only need one or two files out of a large download, such as a single spreadsheet or configuration file in a long list of assets.

• Peek inside unfamiliar archives without installing a separate utility.
• Extract only the file you need instead of expanding everything.
• Repack archives into a format that your target system understands.

Because everything runs inside the browser, you can use these tools on locked-down machines or temporary workstations as long as they have a modern web browser and an internet connection to load the page.

4. Understanding DNS, SPF, and Email Deliverability

DNS records control how your domain behaves on the internet. When email deliverability is poor, it is often because SPF, DKIM, or DMARC records are missing or misconfigured. The DNS Toolkit in File Tools helps you inspect these records using DNS-over-HTTPS resolvers.

You can enter a domain name and see all the relevant records in one place. The tool explains how many DNS lookups an SPF record performs and whether it might cause problems with strict receiving servers. For many small domains, fixing a single SPF mistake is enough to reduce spam-folder issues.

• Look up A, AAAA, MX, TXT, CNAME, NS, SRV, and CAA records.
• Check SPF flattening, includes, and redirect chains.
• Verify that DMARC records exist and are syntactically valid.

These tools do not replace professional monitoring, but they make it much easier to spot obvious configuration issues before opening a support ticket with your mail provider.

5. Parsing Logs and Splitting Huge Files

Server and application logs grow quickly. When something goes wrong, you usually have to work with files that are hundreds of megabytes or more. File Tools includes a Log Parser and a File Splitter that are designed to handle these scenarios in the browser.

The Log Parser can recognize common web server formats and summarize traffic by IP address, endpoint, response code, and geographic information. The File Splitter is a lightweight companion that breaks extremely large text files into smaller chunks so you can open them in other tools.

• Split multi-gigabyte logs into manageable pieces by line count.
• Analyze request patterns, slow endpoints, and error spikes.
• Export CSV summaries for further analysis in a spreadsheet.

Because the data never leaves your browser, you can safely explore logs from staging or production environments without copying them to external services.

6. When to Use Browser Tools vs. Installed Software

Browser-based tools excel at quick, focused tasks. They are ideal when you do not have admin rights, when you are jumping between machines, or when you simply want to avoid installing another single-purpose program. If you only merge PDFs once a month, it rarely makes sense to install a heavy desktop application.

Installed software still has a place for very large workloads, automation, or situations where you must process files in bulk around the clock. In those cases, combining File Tools for ad-hoc work with command-line or server-based tools for continuous jobs is often the most practical approach.

File Tools focuses on the everyday, in-the-moment problems: “I need to compress this image,” “I need to inspect this log file,” or “I need to check the DNS records for this domain.” If a particular task becomes part of your daily workflow, you may eventually outgrow the browser and move to dedicated software—but for many people, that day never comes.
