How to use it
- Drop one or more images, or paste one with Ctrl+V.
- Pick a target size such as 50 KB, or switch to Quality mode.
- Wait a moment while each image is compressed on your device.
- Download files one by one, or all at once.
Why size targets beat quality sliders
Most compressors ask for a quality percentage, which leaves you guessing and re-trying until the file is small enough. Forms and portals care about one number: the maximum KB. This tool works backwards from that number to the best quality that fits, every time.
Frequently asked questions
How does it hit an exact size like 50 KB?
It searches for the highest JPEG quality that stays under your limit, so you get the best-looking image the size allows. If even low quality is too big, it gently reduces the pixel dimensions.
Will compression reduce quality?
Some detail is always traded for a smaller file, but the tool keeps as much quality as possible. Photos usually look the same on screen down to 100 to 200 KB.
Is there a file limit?
No limit on the number of files. Very large images (over 50 megapixels) may be slow on older phones because everything runs on your device.
Are my images uploaded?
No. Compression happens in your browser. Nothing is sent to a server, so it's safe for ID documents and personal photos.
