JSM Image: Free image tools that never upload your files

Resize, convert, compress, crop and rotate images right in your browser — JPG, PNG, WebP, AVIF, GIF, SVG, HEIC, single or batch with ZIP download. Nothing is uploaded, ever: everything runs locally on your device, and EXIF/GPS data is stripped automatically. Plus a free privacy toolkit — redact text, blur plates, pixelate details, cover faces with emoji — for sharing photos without their secrets. No accounts, no watermarks, free.

Hi Product Hunt 👋

I'm a solo maker, and I built JSM Image because I didn't trust online image tools with my own photos. Every "free converter" I tried wanted me to upload my files to someone else's server — for a resize!

So I built the opposite: every tool on JSM Image runs 100% in your browser. Nothing is uploaded, ever. You can even disconnect from the internet after the page loads and it keeps working.

What it does:

• Resize / convert / compress JPG, PNG, WebP, AVIF, GIF, SVG, HEIC

• Batch processing with a smart-pick that chooses the best format per file, ZIP export

• Crop, rotate, straighten, social-media presets

• Privacy tools: redact, blur, pixelate, EXIF remover, emoji face cover

• EXIF (GPS + camera data) stripped automatically on conversion

No accounts, no watermarks, no file-size games — free.

I'd love your feedback: which image task do you still have to upload files for? That's the next tool I'll build.

That's a wrap on day one — thank you to everyone who stopped by, upvoted, or tried the tools today. 🙏

Quick recap: JSM Image is free image tools that run 100% in your browser. Nothing is ever uploaded — not for a resize, not for a blur, nothing — and EXIF/GPS data is stripped automatically. Plus a privacy toolkit (redact, blur, pixelate, remove EXIF, emoji face cover) for sharing photos without their secrets. No accounts, no watermarks.

If you tried it today, one question I keep asking: which image task do you STILL have to upload files for? That's the next tool I'll build. Appreciate every answer.

Onward. 🚀
