Other “privacy-first” image tools still upload your file to a server. ImgShifter doesn't. Here's a 30-second test you can run yourself, with nothing to install.

Frequently asked questions
Short answers for image workflows, privacy, and supported formats.
Are my images uploaded to a server?
No. PNG, JPG, WEBP, AVIF, compression, crop, and resize all run in your browser using the Canvas API and WebAssembly. You can verify by disconnecting from the internet after the page loads - the tools keep working.
What about HEIC, SVG, TIFF, and RAW?
All of them run in your browser. HEIC decodes through a WebAssembly module, SVG converts in both directions on a canvas, TIFF decodes with UTIF.js in a background worker, and camera RAW files (CR2, CR3, NEF, ARW, DNG, and more) are developed by LibRaw compiled to WebAssembly. The How it works page has the full per-format breakdown.
Is ImgShifter free to use?
Yes. Every tool is free with no signup, paywall, or hidden limits - process as many images as you need.
Do I need an account?
No. ImgShifter is built for a no-signup workflow so you can process images immediately.
Does compression happen client-side?
Yes. JPG, PNG, WEBP, and AVIF compression runs in your browser with WebAssembly builds of MozJPEG, libwebp, and libavif, plus Oxipng for lossless PNG, with live preview and file-size stats.
It started in a hospital bed
Why ImgShifter exists.
A while ago I was in a hospital bed, trying to send my employer the medical certificate they needed before they would approve my sick leave. I took a photo of the paper certificate with my iPhone, opened the HR portal on the same phone, tapped upload, and the portal threw back a red error. It only accepted PNG, JPG, or PDF. My iPhone had quietly saved the photo as .heic.
The only fast option I could find uploaded my photo, a private medical document, to a server I'd never heard of, run by a company I knew nothing about. I clicked the button anyway, because I was sick and I needed the leave approved. That discomfort is the entire reason ImgShifter exists.
So every tool here does the work on your device, and you shouldn't have to take my word for it. Open HEIC to JPG, the tool that started all of this, disconnect from the internet, drop a file in, and watch it work.
Your images stay yours.
Drop a file and see for yourself. No signup, no upload, no watermark.
