    Common size limits

    WhereTypical limitTry

    Always check the exact requirements of the form you’re filling in – some also need specific pixel sizes, which you can set with Maximum width or height or our Image Resizer.

    Lossy vs lossless

    JPG, WebP and AVIF are lossy: they throw away detail you’re unlikely to notice to make files much smaller. PNG is lossless: it keeps every pixel, which is best for screenshots, logos and text but makes large photo files.

    Frequently asked questions

    How do I reduce a photo to 50 KB or 20 KB?

    Choose Target size and tap 50 KB (or 20 KB). The compressor tries different quality levels and, if needed, makes the photo slightly smaller in pixels until it fits under your limit. This is useful for government forms, exam applications and job portals.

    What quality should I use?

    75–85% is a good balance for most photos: the file shrinks a lot and the difference is hard to see. Go lower for thumbnails or previews, higher for prints.

    Which format makes the smallest files?

    AVIF is usually smallest, then WebP, then JPG. “Smart” picks JPG for normal photos and WebP for images with transparency. Use JPG when a website or form only accepts JPG.

    Can I compress PNG images?

    Yes. PNG is a lossless format, so the biggest savings come from converting to JPG or WebP. Images with transparent areas keep them when saved as WebP or PNG.

    Why does it say “Already optimised – original kept”?

    Some images are already well compressed. If re-saving would make the file bigger, the compressor keeps your original instead. Lower the quality or the maximum size to shrink it further.

    Does compressing remove photo information?

    Yes – the compressed image doesn’t include the original EXIF metadata such as camera details and GPS location, which is good for privacy when you share photos online.

    Are my photos uploaded?

    No. Compression happens entirely in your browser, so it’s fast and private.

    How many images can I compress at once?

    Up to 100 images, each up to 40 MB. Download them one by one or together as a ZIP file.
