Compress image to 500 KB free
A 500 KB limit is typical for blog images, listing galleries and presentations. Instead of guessing a quality slider, this page is already set to a 500 KB target: drop the image and you get a file that fits, with the exact size shown before you download. Expect a 1600–2000 px photo with no visible loss.
Drag the handle. Zoom your browser (Ctrl +) to inspect fine detail at 100%.
Exact size, not a guess
The compressor tries progressively smaller settings until the file is under 500 KB, then stops, so you keep as much quality as the limit allows.
Private by design
The image is processed on your own device. Nothing is uploaded, nothing is stored, and it works offline once the page has loaded.
Batch and formats
Up to 50 images at once, JPG, PNG, WebP, AVIF and iPhone HEIC in; download one by one or as a ZIP.
Frequently asked questions
Will quality drop at 500 KB?
For most photos no. The target search keeps the highest quality that fits; if the result is softer than you like, reduce the pixel size a little first and run again.
Which format reaches the size most easily?
JPG for photos and scans, WebP if the site accepts it (about 25 percent smaller than JPG), PNG only for graphics with flat colours.
Is the image uploaded?
No. Compression runs in your browser; the file never leaves your device.
