This page opens the compressor with JPG selected as the output format, so each photo is saved as a JPG once it is compressed. JPEG and JPG are the same format, so a file with either extension gives the same result. You still choose the size limit.
JPG has no transparency, so a photo with see-through areas, such as a cut-out or a logo, needs WebP to keep them. Pick WebP under Save as for that picture. The compress image tool shows every output option.
How to compress a photo to a target size
- Drop one or more photos onto the box (or tap it to choose).
- Pick the maximum size the website or form allows.
- Download each photo, or all of them as a ZIP.
Questions
Is JPEG the same as JPG?
Yes. JPEG and JPG are two names for the same format, and files with either extension open the same way in image viewers and editors.
Does compressing a JPG again lower its quality?
Yes. Each save of a JPG compresses the picture again, so the loss builds up. Compress from the original file, and keep that original for later edits or new copies.
Will my photos be uploaded?
No. The compression runs in your browser with the canvas API. Your photos never leave your device, which is also why it is fast.
How does it hit an exact size?
It tries different quality levels (a binary search) until the file is just under your target. If even low quality is too big, it also reduces the pixel dimensions a little at a time.
Why did my PNG turn into a JPG or WebP?
PNG is lossless, so it cannot be squeezed to a target size. Photos are re-encoded as JPEG. Images with transparency become WebP so the transparent areas survive; where your browser cannot save WebP, they become PNG instead.
Is the location data removed?
Yes, from every re-encoded photo: drawing it on a canvas leaves out its GPS location and camera details. With Best for each photo, a photo already under your limit is handed back unchanged and keeps its metadata. Use Remove photo location for that.
