Compress an image to 300 KB

300 KB is a comfortable size for photos that people will view full screen. Shrink 5 MB camera photos to a fraction of their size without visible quality loss.

Files stay on your device. Nothing is uploaded.

How to use: Compress image to 300 KB

  1. 1Choose the photos you want to share. You can add many at once.
  2. 2The target is pre-set to 300 KB. Pick WebP for websites if you like.
  3. 3Press "Compress".
  4. 4Download the photos or a single ZIP.

Good uses for 300 KB photos

  • Email: send a dozen photos without hitting attachment limits.
  • Online shops and WhatsApp Business catalogues: product photos that load quickly on mobile data.
  • Blog posts and websites: large images that still keep pages fast.
  • Property and car listings: sites often reject or slowly process huge camera files.

Why not send the original?

Original phone photos are much bigger than any screen needs. Sending them wastes your data, fills the recipient’s storage and slows down websites. A 300 KB version is visually the same on screen.

Keep the originals

Compression creates new files; your originals are never changed. Keep the full-size versions for printing and archives.

Frequently asked questions

How much smaller will my photos be?

A typical 12-megapixel phone photo is 3–6 MB, so 300 KB is about a tenth of the size or less, and it still looks sharp on phones and laptops.

Should I choose WebP?

For your own website or online shop, yes. WebP looks better than JPG at the same size. For email attachments and forms, keep JPG because everyone can open it.

Is there a limit on how many photos I can compress?

You can add up to 50 photos at a time, with no daily limit.
