This free image compressor and converter resizes and re-encodes your photos to JPG, PNG, WebP or AVIF — entirely in your browser. Modern formats like WebP and AVIF can cut file size dramatically at the same visual quality, which is ideal for faster web pages and smaller uploads.
Nothing is uploaded: images are decoded with the browser's own pipeline (which also bakes in correct orientation and drops metadata like GPS), processed on a canvas, and handed straight back to you. Set an exact max file size and we auto-tune quality to fit.
Frequently asked questions
Is it free?
Yes — free, no sign-up, no watermark, no file limit.
Are my images uploaded?
No. Everything runs in your browser; your images never reach a server.
Which formats are supported?
Output to JPG, PNG, WebP or AVIF. WebP/AVIF depend on your browser — if unsupported, it falls back to PNG and tells you.
Can I hit an exact file size?
Yes. Turn on a max file size and we auto-tune quality (and downscale if needed) to fit.
