Half a megabyte is generous — nearly any photo fits with imperceptible loss. It's the sweet spot for email attachments, CMS media libraries and listing sites with per-image caps.
Getting the best result at 500 KB
- Even 12–48 MP phone photos usually land under 500 KB at high quality once resized to 2048 px.
- Batch mode compresses a whole shoot to the same budget in one go — useful for listings and galleries.
- If the file is already under 500 KB the tool simply picks the highest quality that fits.
Frequently asked questions
How does the tool get my image under 500 KB?
The tool binary-searches the JPG/WebP quality at your image's dimensions, and if even the lowest quality is too big it steps the dimensions down until the file fits under the target.
Why is my photo 8 MB in the first place?
Modern phone cameras save 12–48 MP images with light compression. Most uses need far fewer pixels — resizing to 2048 px and re-encoding keeps the look while cutting 90%+ of the size.
Is my image uploaded anywhere?
No. Compression runs entirely in your browser — your image is processed on your own device and never uploaded to a server.
