How it works
Why compress images to 500 KB?
Blogs and online stores often want images under half a megabyte. Hit 500 KB with quality good enough for web display and light printing with search for best quality.
How target-size compression works
This tool re-encodes your image repeatedly, searching for the highest quality that still fits under 500 KB. Choose the output format, JPG, WebP, PNG or AVIF, and the best match wins.
Which output format should I pick?
JPG is the safest default for photos. WebP keeps transparency and compresses well. PNG suits graphics and text. AVIF gives the smallest files in modern browsers.
Is compression private?
Your image is compressed to 500 KB locally in your browser. The file never leaves your device.
Batch compress images to 500KB
Compress a batch of product or blog photos to under 500 KB each. Free, private, batch ZIP, and processed entirely in your browser.
Frequently asked questions
Is 500KB good enough for a website hero image?
Yes. Under 500KB loads quickly on most connections while keeping photos sharp on large screens at balanced quality.
Should I resize before compressing to 500KB
Yes if the hero is larger than needed. Shrink to display pixels first, then compress to 500KB for best sharpness at smallest size.
Can I batch compress many images to 500KB without uploading
Yes. Add your folder, pick 500KB target, and compress together. Each image is searched locally for best quality under 500KB and you can download a ZIP.
