Compress photos to 300 KB free, one or a whole folder. Sharp JPGs for websites, listings and forms, made in your browser with no upload.
Compressed in your browser. Free, no sign-up, photos never leave your device.
Drop photos, or click to browse
JPG, PNG, WebP or HEIC. Each photo is compressed to 300 KB as soon as you add it.
Quick answer
BatchSet compresses photos to 300 KB free and entirely in the browser, one at a time or a whole folder, with no upload and no sign-up. It keeps the highest JPG quality that fits 300 KB, which stays sharp at web sizes, and scales a photo down only when quality alone is not enough. It suits website and CMS image fields, listings and newsletters that ask for images under 300 KB, and the batch downloads as one ZIP.
Three quick steps — free, private, right in your browser.
Drop a whole folder of JPG, PNG, WebP or iPhone HEIC photos, or click to pick them.
The tool keeps the highest JPG quality that still fits 300 KB. A photo is scaled down only if quality alone is not enough, and each card shows the final size and pixels.
Download them all as one ZIP, ready to upload to your site or listing.
Yes. No account, no credit and no watermark, and no limit on how many photos.
No. The photos are compressed inside your browser and never sent to us, so client photos and unreleased images stay on your computer.
Yes, for screens. 300 KB is enough for a high JPG quality at a typical web width, so most people cannot tell the difference. Full-size phone photos are usually scaled down to fit, which does not show on a web page; photos already sized for the web keep their pixels. The card shows the final size either way.
Big images are the main reason pages load slowly, especially on phones. Many CMS guides, listing sites and newsletter tools set a cap around 300 KB so pages stay fast without photos looking soft.
If your site shows images at a fixed width, resize to that width first with the Image Resizer, then compress here. Smaller dimensions let the same 300 KB carry a higher quality.
Yes. That is what the tool is built for: add the folder, each photo is taken to 300 KB on its own, and one ZIP comes back.
