Compress Images Online
By quality or to a target file size. Your files never leave your device.
Frequently asked questions
How do I compress a photo to a specific size, like 1 MB?
Choose “To file size”, enter the number and the unit — KB or MB — and add your photos. The compressor encodes each image a few times at different qualities and keeps the highest quality that fits the limit.
Why is the file smaller than the size I entered?
The size is chosen so the file never goes over the limit, so it usually ends up a bit smaller. Kilobytes and megabytes are decimal (1 MB = 1,000,000 bytes) so the file passes the check on any website.
What if the image can't be compressed to that size?
If the file is still too large even at the lowest quality, the smallest version is saved and its row shows a hint. Reduce the image's dimensions in that case — resolution affects file size the most.
Will the quality drop a lot?
At the default quality of 75 the difference is usually hard to notice on photos, while the file gets much lighter. The lower the quality, the smaller the file and the more visible the compression artifacts.
Can I compress a PNG?
Yes, but PNG is lossless, so it can't shrink much. If you don't need transparency, choose JPG; if you do, choose WebP — it keeps transparency and is many times smaller.
Why didn't the file get smaller?
If the original was already heavily compressed, compressing it again gains little. Lower the quality or choose WebP — each file's row shows how its size changed.
What happens to the location and the date taken?
By default the capture date is kept, while the location, phone model and other details are removed — which also trims the file a little. Tick “Keep all metadata” to copy everything.
Is it safe to compress my photos here?
Yes. The site only downloads the tool itself; your images are processed in your browser and are never sent to a server.
