How to compress a photo to 500 KB
A 500 KB limit is generous for an image: enough for a detailed photo or a clear picture of a full document page. This page is set to 500 KB and lowers quality only as far as needed, so many pictures show no visible change.
Add your photos, one or a whole batch.
Check the size box shows 500 KB.
Click Compress images and download the JPG, or the ZIP for a batch.
A generous limit for photographs
500 KB caps appear on profile and gallery uploads, support-ticket attachments, classified listings and application portals that want a clear image of a document. Unlike the 20 to 50 KB limits written for passport photos, half a megabyte does not force a visible trade-off for most pictures. A photo that has been cropped, or one taken at a modest resolution, typically fits by lowering JPEG quality alone and keeps its full pixel dimensions; a very detailed full-resolution shot may be scaled down a step.
A JPG that is already under 500 KB is not re-encoded at all. It is returned as it was, so running a mixed folder through this page only changes the files that needed it.
Batches for email and messaging
This size suits sending sets of pictures. Ten photos at 500 KB each total about 5 MB, which fits in a single email on most mail services, where ten originals straight from a phone often would not. Add the whole set at once: each image is fitted on its own, the note under each shows its final size, and the set downloads as one ZIP with _under_500kb added to every file name. The originals on your device are not altered; the compressed copies are new files.
