Compress JPEG Files Online, Free and In Your Browser

Compress JPEG and JPG images in your browser. Pick a quality, see the saving on every file, download one at a time or all as a ZIP. Free, no signup, nothing uploaded.

Free — no signup, runs in your browser

Compress as many images as you like on your device — nothing is uploaded.

100% private. Compression runs in your browser — your images are never uploaded.

Quick answer

BatchSet's JPEG compressor reduces the file size of JPG and JPEG photos for free, right in your browser, with no signup, no upload and no watermark. You set the quality from 10 to 100 and see the resulting size on every file before downloading, one at a time or all together as a ZIP. If instead you have to hit an exact limit, such as 100 KB for a form, use the compress-to-size pages, which search for the highest quality that fits.

Frequently asked questions

Is the JPEG compressor free?+

Yes. Compression runs in your browser, so it costs nothing to run and nothing to use. There is no watermark and no signup. Signing in with a free account raises the per-file size limit.

Are my photos uploaded anywhere?+

No. The files are read and recompressed inside the browser tab and never sent to a server. You can watch the network tab and see nothing leave.

What is the difference between this and the 'compress to 100 KB' pages?+

This page gives you a quality setting and shows what size that produces. The target-size pages work the other way round: you name the size in KB and the tool searches for the highest quality that fits. Use those when a form or portal enforces a hard limit.

Does compressing a JPEG again lose quality?+

Yes. JPEG is lossy, and each re-save throws away a little more detail, so the losses compound. Always compress from the original rather than from an already compressed copy.

Does the compressed file keep its EXIF data?+

No. The image is re-encoded through a canvas, which drops EXIF, including camera settings and GPS. If you want to inspect or strip metadata deliberately, use the EXIF metadata tool.

Should I use JPG or WebP for a website?+

WebP is usually a good deal smaller than JPG at the same visual quality and every current browser supports it. Keep JPG when something downstream only accepts JPG, such as a print shop or an older CMS.
