How to get an image under 500 KB
- 1
Drop in your photos
Add camera photos, product shots or scans – one at a time or a whole folder.
- 2
Compression is automatic
Each image keeps up to 2560 px on its longest side and is saved as JPEG at the highest quality below 500 KB.
- 3
Need full resolution?
Remove the maximum width in the settings to keep every pixel; the quality search then works a little harder to fit.
- 4
Download your images
Get single files or one ZIP with the same folders you started with.
When a 500 KB limit makes sense
Marketplaces, property and car listings, portfolio sites, forums and many company systems limit uploads to around 500 KB per image. It is also a good budget for photos you send to clients by email: large enough to zoom in, small enough that a dozen photos don’t clog an inbox.
At 2560 px – sharper than a QHD monitor – a well-exposed photo fits into 500 KB with plenty of detail, so the limit rarely shows.
Resolution versus compression
Every limit is a trade-off between pixels and compression. For screens, a slightly smaller image at high quality looks better than a huge image squeezed hard. That is why this page caps the size at 2560 px by default: the quality search can then keep the JPEG quality high.
If the photo will be printed, keep more pixels by raising or removing the maximum width, and consider a larger target such as 1 MB.
Product and listing photos
For an online shop, photos under 500 KB keep product pages fast while still allowing zoom. If your platform accepts WebP, switch the output format – WebP keeps more detail at the same size. Need a clean white background first? Use the background remover and then compress the result here.
Frequently asked questions
How do I compress a 5 MB photo to 500 KB?
Add it to this page. It is scaled to at most 2560 px and compressed until it fits, which typically takes a 5 MB photo to between 400 and 500 KB.
Can I keep the original resolution?
Yes. Clear the maximum width and height in the settings. Very large, detailed photos may then need a lower quality to fit, so compare the result before you use it.
Does it work with PNG files?
Yes, PNG files can be added, but they are saved as JPEG (or WebP/AVIF if you choose), because lossless PNG can’t be compressed to a target size.
Are my photos uploaded?
No. Everything runs in your browser, so you can safely compress private or unreleased photos.

Compress to 200 KB
200 KB is enough for a sharp full-HD photo – and small enough for most upload forms, emails and web pages. Set it once and every image in your batch fits.
Compress to 1 MB
Phone photos are often 3–10 MB – too big for many upload forms. Bring them under 1 MB at up to 4K resolution, so they still look great when someone zooms in.
Remove background
Cut out people, products and pets automatically. The AI runs on your own device, so your photos are never uploaded – and downloads are full resolution, with no watermark.
Resize images
Set a maximum width or height and every image is scaled down proportionally – and compressed at the same time.
