Compress a photo to 200 KB without uploading
200 KB is a middle ground: small enough for many email and form uploads, large enough that everyday photos often need only a quality change, not a heavy resize.
No upload. Files never leave your device.
Drop images here
JPEG, PNG, WebP, AVIF, GIF, BMP, and TIFF are welcome. Multiple files are fine. Output is always JPEG so the size cap can be met.
Results
No files yet. Nothing is sent to a server when you add them.
Email, coursework, and support attachments
People are often told to keep a file small for email, a homework dropbox, or a support ticket, without being given a single official number. This page uses 200 KB as a concrete cap that is still comfortable for a typical snapshot or screenshot.
If you are attaching several pictures to one message, staying around this size helps the whole message stay manageable. The page outputs JPEG, which most mail and form systems accept. Work runs on your device.
Frequently asked questions
Does this upload my photo?
No. Compression runs in a Web Worker on your device. Nothing is sent to a conversion server.
Is 200 KB a good size for email or a class upload?
It is a practical middle size for a single photo or screenshot. Message and course systems set their own limits, which this page does not try to quote. If you were given a different number, use the matching size page or the custom cap on the main compressor.
Will a screenshot stay readable?
Often yes at 200 KB, especially if you crop to the relevant window first. Fine text can soften if the original was very large and the page has to resize it. If type looks muddy, try cropping, then compress again.
How does the tool decide whether to resize?
It searches JPEG quality first. Only if the file is still over 200 KB at a low quality setting does it reduce the dimensions and search again.
Can I compress many files at once?
Yes. Add a batch, compress, then download a ZIP — useful when one email or ticket needs several pictures.
