Free online image tools that never upload your files
Tooljar is a growing collection of 9 free image tools built around one simple promise: your files never leave your device. Most "free" online converters and compressors work by uploading your photo to a server, processing it there, and sending it back. That means your personal pictures — ID photos, signatures, private snapshots — sit on a stranger's computer, if only for a moment. Every tool here works differently.
Using the modern Canvas API built into your browser, Tooljar does all the work locally. When you drop an image onto a tool, it is read straight into the page, processed on your own machine, and handed back to you as a download. Nothing is transmitted, nothing is stored, and there is no account to create. It is faster too, because there is no upload or download round trip — and it even keeps working offline once the page has loaded.
What you can do here
The suite covers the everyday image jobs people search for most, whether you are preparing a document, posting to social media, or building a website:
- Compress — shrink JPG, PNG and WebP files to hit an email, website or upload-form size limit.
- Resize — set an exact pixel width and height for avatars, social posts or passport photos.
- Crop — trim to a square, a 16:9 thumbnail, or any custom selection.
- Convert — move between JPG, PNG and WebP to suit the web, a form, or transparency.
- Rotate & flip — fix a sideways scan or mirror a selfie.
- Image to PDF — combine several photos or scans into one tidy PDF.
- Watermark, colour palette and Base64 — protect your work, pull hex colours from a photo, or inline an image in code.
Made for forms, social media and the web
A lot of people arrive here with a very specific task — a scholarship portal that demands a photo under 50 KB, an Instagram post that keeps getting cropped, a signature that has to be a 20 KB JPG. The exam-form compressor, the passport photo maker and the Instagram resizer are set up with the right defaults for exactly those jobs, so you are not left guessing at settings. Whatever brought you here, the tool is free, private, and ready in seconds.
Are my images uploaded to a server?
No. Every Tooljar tool runs entirely in your browser using the Canvas API. Your images never leave your device — there is no server upload.
Is Tooljar free to use?
Yes, completely free. No sign-up, no limits, and no watermark on your output.
Which image formats are supported?
JPG, PNG and WebP are supported across the tools, plus image-to-PDF export. Convert lets you move between JPG, PNG and WebP.
Do I need to install anything?
No. Tooljar is a website — open a tool, use it, and close the tab. There is no app, extension or download, and it works offline once a page has loaded.
Does it work on my phone?
Yes. Tooljar works in any modern browser on desktop, tablet or phone — there is nothing to install.
