JPG works everywhere. WebP is smaller. PNG keeps transparency but is large. iPhone HEIC photos are saved as JPG.

How it works

At 500 KB you can keep a lot of detail. This page fits photos within 2560 pixels and finds the highest JPG quality that stays under 500 KB, so photos still look great on large screens.

It's a good setting for marketplace listings, real estate photos and blog images, where you want quality without slow loading.

Where a 500 KB limit shows up

Job and school applications: profile photos and scanned documents often have to stay under 500 KB.
Marketplace and real estate listings: many sites cap each photo, and smaller files load faster for buyers.
Government and visa forms: limits vary a lot; check the note next to the upload button.
Blogs and websites: keeping images around or under 500 KB is a common rule of thumb for fast pages.

How big can a photo be at 500 KB?

Longest side	At 500 KB	Good for
2560 px (this page)	High quality for most photos; very detailed scenes get a slightly lower quality to fit	Large screens, listings, zooming in
1920 px	Comfortable fit at high quality	Full HD screens, blogs
1200 px	Well under the limit	Email, small website images

This page counts 1 KB as 1,000 bytes, so results also fit forms that count 1 KB as 1,024 bytes.

Step by step

Add your photos. You can add many at once.
Each one is fitted within 2560 pixels and saved at the highest JPG quality that stays under 500 KB.
Check the result with “Compare”. If a form also asks for an exact width and height, open Settings and choose “Exact size”.
Download them one by one, or all together as a ZIP.

If it still won't fit

Very detailed photos (leaves, gravel, noisy night shots) compress less. If quality alone can't get under 500 KB, the photo is made a little smaller and the card tells you the new size.
Need it even smaller? Try Compress image to 200KB or 100KB.
Not sure what you have? Check the image size to see a photo's pixels and file size first.

Questions

How much smaller will my photos get?

A typical 4 MB phone photo drops to under 500 KB, around 85–90% smaller, with very little visible difference.

Can I compress 50 photos at once?

Yes. There's no daily limit. Larger batches just take longer because the work happens on your device.

What about PNG screenshots?

They're saved as JPG here. For screenshots with text, JPG at this size still looks clean.
