Compress Image Online
This is the general-purpose ImageFry compressor: drop any JPG, PNG, or WebP, set the size you need in KB, and download a smaller copy at the best quality that fits. Unlike upload-based compressors, your image is processed on your own device — faster, private, and it works even on a weak connection.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
How does image compression work?
JPEG compression discards visual detail your eye is least likely to notice, trading file size against quality. This tool tests multiple quality levels in a binary search to find the highest one that fits your KB target — the same result as manual trial-and-error, done in seconds.
Which is better for compression, JPG or PNG?
For photos, JPG — it reaches far smaller sizes at similar visual quality. PNG is lossless and better for screenshots, logos, and graphics with sharp edges or transparency. This tool outputs JPG because KB-limited uploads virtually always expect it.
Is there a file size or count limit?
No practical limit — your own device does the work. For many files at once, use the bulk compressor page.
