About this tool
Corporate mail servers frequently limit combined attachments to 10–25 MB, and mailing lists can be even stricter. Compressing each image to roughly 100 KB lets you attach dozens of photos without bouncing or ballooning your recipient's inbox. This landing sets the compressor to a 100 KB target and works well with holiday snaps, event photography, or business documentation photos. Encoding runs locally in your browser.
FAQ
No. Compress here, then attach the files in your normal email client.
100 KB keeps combined attachments small even when you send many photos, and inline previews load fast on mobile.
For most business photos, yes. For high-fidelity portfolio images, use the 500 KB or 1 MB landing.
Modern email clients handle WebP, but some older desktop clients do not. Prefer JPG if unsure.
No — everything is local.

How it works
- Add the image you plan to attach.
- Compression targets about 100 KB so the message is less likely to bounce on mailbox limits.
- Preview, then download and attach the smaller file in your mail client.
Tips

- Local — No uploads, no scanning of your images.

Limitations
- 100 KB per image is a soft target — total attachment size still depends on how many you send.
- Not all email servers enforce the same caps; check your recipient's limits.
- We do not send email — you download the images and attach them yourself.
- Very large source photos may take a moment to re-encode.
- About 25 MB per file, processed one at a time.
