How to compress an image to 500 KB
Drop the image and it is compressed to the highest quality that fits under 500 KB, automatically. The page tries several quality levels and keeps the best one that meets the limit, so you do not have to guess. Batch drop is fine: each file gets its own best quality. Check the before/after view and download.
If it cannot reach 500 KB
Large photos straight from a phone are 3–5 MB at 4000 px wide. Lower the maximum width to 1600 or 1920 px, which is still full-screen size, and most will fit under 500 KB at a good quality.
Where this limit comes up
Email attachments, CMS uploads, marketplace listings and forum avatars often cap files at 200 or 500 KB. Web pages also load faster when images stay under this size.
Nothing is uploaded
Compression happens on your device in the browser. The photo is never sent to a server, so it is fast, private and has no file limit.
