Compress an image to 500KB
500 KB gives you enough headroom to keep a high-resolution photo looking sharp while still staying well under most upload limits. Drop your image below and we'll find the highest quality that still fits.
Your images stay on your device. Compression happens in your browser and files are never uploaded to our servers.
Where a 500 KB limit shows up
Portfolio and gallery uploads
Photography portfolios and gallery platforms often allow larger files than a typical form, but still cap uploads around 500 KB to 1 MB so pages load quickly for visitors browsing dozens of images.
Print-adjacent digital proofs
A 500 KB image holds enough detail to review composition, color, and sharpness on screen, without sending the full multi-megabyte original over email or a slow connection.
CMS and blog media libraries
Content management systems frequently recommend keeping hero and header images under 500 KB, since heavier files slow down every page they appear on.
Questions about this size
Is 500 KB enough to keep full quality?+
For most photos, yes. 500 KB rarely requires any resolution loss, so the compressor usually only needs to adjust quality, not shrink the image.
Should I use JPG or WebP at 500 KB?+
WebP typically produces a visibly cleaner result at 500 KB than JPG, since it has more room to preserve detail. Use JPG under Advanced options only if you need broad compatibility.
What if my original is already under 500 KB?+
We tell you the image already meets your target instead of re-encoding it unnecessarily, so you never lose quality for no reason.
