Why this exact limit matters
Marketplaces cap image sizes to keep listing pages fast, and sellers with dozens of products feel the cap on every upload. Editing each photo by hand in a desktop tool does not scale past the first few listings.
A fixed target turns bulk image preparation into a repeatable step: same ceiling, every file, no per-image editing. 500 KB is a generous limit that still catches full-size phone photos, and this page is preset to exactly that ceiling.
How to compress to 500 KB
- Drop your image into the box above — it stays on your device.
- Confirm the target: under 500 KB as PNG.
- The tool optimizes the PNG losslessly and, if the target cannot be met, also prepares a JPEG alternative that does fit. Dimensions are left at their original size unless the target demands otherwise.
- Preview the result, compare it with the original if you want, and download — the filename carries its actual size.
Tip: For product photos, fill in the marketplace's recommended pixel dimensions along with the size limit — meeting both at once is what the dual-constraint input is for.
Frequently asked questions
Will compression hurt my listing's image quality score?
Marketplaces score zoom sharpness, and this tool maximizes quality within your stated ceiling. Give it the largest ceiling your marketplace allows rather than the smallest that passes.
Why can PNG be hard to shrink to a small size?
PNG is lossless: it never discards image data, so its size floor depends on the amount of detail in the picture. This tool optimizes with OxiPNG and reduces dimensions, and tells you honestly when the target is unreachable losslessly.
Is my image uploaded to a server?
No. All decoding and encoding runs locally in your browser via WebAssembly. There is no server-side pipeline, no storage, and no way for us to see your file.
