Image Compressor

Getting photos under a size limit without ruining them

Upload limits are a daily frustration. Government portals, exam applications, job sites and email attachments often reject photos above 50 KB, 100 KB or a few megabytes, while phone cameras produce files several times larger. Compressing reduces the file size by storing the image more efficiently and dropping detail your eye is unlikely to notice. Done well, the result looks almost identical on screen.

The quickest way to meet a strict limit is to enter a target size. The compressor then searches for the highest quality that fits under it, so you do not have to guess. If the target is very small, reducing the image dimensions first helps a lot, because a photo taken at 4,000 pixels wide does not need that much detail for a form that displays it as a small thumbnail. Setting a maximum width of around 600 to 1,000 pixels is usually enough for application photos.

Pick the right format for the job. JPG is the best all-round choice for photographs and is accepted everywhere. WebP produces smaller files at similar quality and works well for websites, but some upload forms still reject it, so check what the site accepts. Avoid compressing the same image again and again, since each round can add visible blockiness; start from the original instead. You can compress several photos at once, which is handy for product listings or event pictures. Your images are processed on your own device and are never uploaded, so personal documents and ID photos stay private. Keep the original file safe in case you need a sharper version later.
