Why use FreeTools?
Your files stay on your device
Unlike most "online" tools that upload your files to a third-party server, every operation here runs in your web browser using modern JavaScript APIs. Great for sensitive documents, private photos, and anything else you'd rather not hand over.
Fast by default
No upload wait. No queue. The moment you drop a file, processing starts. For a 5 MB PDF or a photo, most tasks finish in under a second.
No tracking your work
We use lightweight analytics to count page visits, but we never see the content of the files you process. There's no server-side record of what you merged, resized, or prettified — because there's no server-side processing at all.
Built for quick jobs
Every tool is designed around a single task, so you can open it, drop your file, and move on. No dashboards, no onboarding, no "create your first project" walls.
Frequently asked questions
Are these tools really free?
Yes. Every tool is free with no daily limits, no watermarks, and no signup. The site is supported by unobtrusive ads. A paid Pro tier (in development) will add bulk-processing features for power users, but the existing tools will always stay free.
Are my files private?
Yes. Every tool processes your files entirely in your browser using
JavaScript and the standard Web APIs (Canvas, File, and libraries
like pdf-lib). Your files are never uploaded to our
servers — because there's no file-handling server. You can verify
this by watching the Network tab in your browser's dev tools.
Do I need to install anything?
No. Open a tool page, drop your file, and start working. It runs in Chrome, Firefox, Safari, Edge, and any other modern browser — on desktop and mobile.
How does this compare to Smallpdf, iLovePDF, or TinyPNG?
Those services upload your files to their servers. That's fine for non-sensitive files, but it's slower and more privacy-intrusive. This site keeps everything local to your browser, so jobs start instantly and your files never travel over the internet.
Is there a file size limit?
Only your device's memory. Most modern browsers handle images up to several hundred megapixels and PDFs of several hundred megabytes without issue. Very large files may take longer to process, but nothing's artificially capped.
What browsers are supported?
Any modern browser released in the last few years works: Chrome, Edge, Firefox, Safari, Brave, Opera. Mobile browsers work too, though big files may be slower on phones.
