Common questions

Everything you need to know.

No. Resizely uses your browser’s built-in image processing — everything happens locally on your device. You can verify this yourself: open your browser’s Network tab (F12 → Network), process an image, and you’ll see zero upload activity. We literally cannot see your files, even if we wanted to.
No account, no email, no signup. Open Resizely, drop your images in, download the optimized files. We don’t track you, and there’s nothing to remember to log into.
Resizely handles individual files up to 100MB. The free tier supports up to 20 files at once; Pro lifts the limit. The actual performance depends on your device, but modern laptops process 1000+ images without issues.
Input: JPG, PNG, WebP, HEIC, HEIF, AVIF, SVG, BMP, TIFF, GIF. Output: JPG, PNG, WebP, AVIF. HEIC → JPG is one of our most popular workflows for iPhone users sending photos to Android or Windows recipients.
Versus TinyPNG: Resizely is fully local — TinyPNG uploads to their servers. We also support batch processing of 20 files; TinyPNG limits free users to 20 per month.

Versus Squoosh: Squoosh only processes one image at a time. Resizely handles batches and adds resize, crop, and preset features Squoosh doesn’t have.

Versus Photoshop: No $20+/month subscription, no install, no learning curve. For 90% of “I just need to compress this image” tasks, Resizely is faster.
Genuinely free, with no catch on the core tools. We’re planning a Pro tier later for batch processing 20+ files, ZIP downloads, and advanced workflow integrations — but the core resize, compress, convert, and crop features will always be free with no limits, no watermarks, and no signup.
