Compressing a photo to 140 KB
A 140 KB limit is a hard ceiling, so the compressor does not guess a quality setting and hope. It searches: it encodes the image several times, measuring each result, lowering JPEG or WebP quality first and reducing the pixel dimensions only when quality alone cannot reach 140 KB. The final file lands at or just under the limit with the most detail that fits, and the before/after slider shows exactly what changed. Everything runs in your browser, so a 12 MB phone photo never leaves your device and the result is ready in a second or two.
Who needs this
Upload forms that reject files over 140 KB: job portals, exam registrations, visa and university applications, government services, marketplace listings and email attachments. It also suits web pages and newsletters where every kilobyte slows the load.
Compress image
Enter any size limit — 20 KB, 150 KB, 1 MB — and the compressor searches quality and dimensions to land just under it while keeping as much detail as possible. Works with JPG, PNG, WebP, HEIC and more.

Frequently asked questions
What if my image is already under 140 KB?
It is passed through untouched when the format matches, so you do not lose quality for nothing. Choose a different output format if you want it re-encoded anyway.
Will the picture still look sharp at 140 KB?
For a typical photo, yes: 140 KB is enough for a clear image at normal screen sizes. Very large or very detailed images are scaled down to fit, and the preview lets you judge before downloading.
Does the result keep the same width and height?
Dimensions are kept whenever the quality search alone reaches 140 KB. Only when that is impossible are the dimensions reduced, proportionally, by the smallest amount needed.
Can I compress several photos to 140 KB at once?
Yes. Drop up to 50 files, run once, and download them individually or as a single ZIP. Each file is compressed independently to the same limit.
How small can I make an image?
Any size above about 1 KB. Type the limit, and the compressor searches JPEG or WebP quality first, then reduces dimensions only when quality alone cannot reach it. The result lands at or just below your target.
Will my photo lose quality?
Some detail is traded for size, but the search keeps the highest quality that still fits. Use the before/after slider to check, and pick a larger target if you need more detail.
Is my image uploaded to a server?
No. Compression runs inside your browser with Web Workers, so nothing is uploaded. With Pro, the installed app also works with no internet connection at all.
