About AllImgTools
AllImgTools is a free set of image editing tools that work entirely in your browser. You can compress, resize, convert, crop, merge, rotate, watermark, blur images, create memes, and convert images to PDF. Nothing gets uploaded. Nothing leaves your device.
Why This Exists
Most image tools online work the same way: you upload your file, their server processes it, and you download the result. That means your photos, screenshots, and documents pass through someone else's server. For a lot of people, that's fine. But for anyone working with sensitive or private images, it shouldn't be the only option.
Modern browsers are more than capable of handling image processing locally. So we built AllImgTools around that idea. Every tool uses JavaScript and the HTML5 Canvas API to do the work right inside your browser tab. No server round-trip, no waiting, no privacy risk.
How It Actually Works
1
Pick a file
Your browser reads the image locally. It is not sent to any server.
2
Processing happens here
JavaScript and the Canvas API handle everything inside your browser. Your CPU does the work, not ours.
3
Download the result
The output file saves straight to your device. No server was involved at any step.
What We Care About
Privacy by architecture, not just policy
Your images never touch our servers. This isn't a promise we have to keep. It's how the code works. There is no upload endpoint. We couldn't access your files even if we wanted to.
Free to use, no account needed
All 10 tools are free. No sign-up walls, no daily limits, no “download 3 more after creating an account” tricks. Just open the page and use it.
Minimal analytics, your files stay private
We use Google Analytics to understand which tools are popular and how people use the site. Your images are never uploaded, tracked, or shared with anyone. See our Privacy Policy for full details.
No watermarks on your output
What you create is what you get. We never add watermarks, branding, or “powered by” tags to your images.
How We Verify Every Size and Spec
Our size guides (Discord, Instagram, YouTube, Facebook, and the rest) are only useful if the numbers are right. A lot of the “image size” articles online copy each other, and errors get repeated for years. We try not to add to that pile. Here is the process behind every spec we publish:
- We test against the real platform. Dimensions and file-size limits are checked by actually uploading to the platform and seeing what it accepts, crops, or rejects, not by repeating what other sites say.
- We cross-check official docs. Where a platform publishes its own guidance (Discord's creator docs, YouTube's channel-art help), we compare our numbers against it and note where real behavior differs from the docs.
- We date and re-check. Platform specs change. Each guide carries a “last updated” date, and we revise the numbers when a platform changes them rather than leaving stale figures up.
- We correct our mistakes in public. When we get something wrong, we fix it and say so. A few recent examples are below.
Corrections we've made
- Discord server banner. An earlier version of our Discord guide listed the server banner as 1920 × 480 (4:1). The correct upload size is 960 × 540 (16:9); the display crops it on mobile. Fixed across the guide.
- Discord sticker file cap. We had the sticker limit as 512 KB in a couple of places. The actual cap is 500 KB. Corrected.
- TikTok safe zones. Our first TikTok numbers used a top safe-zone margin copied from older guides. After testing in-app we corrected the margins and the caption/cover safe area to match what the interface actually covers.
- YouTube banner format. We initially implied GIF banners are rejected; YouTube accepts a non-animated GIF. Wording fixed.
