Compress Images for Email — Make Photos Smaller to Send

Get any photo under 1 MB — so several photos fit in one email. The compressor finds the highest quality that still fits, and only shrinks the dimensions if it has to. Batch many images at once; nothing is uploaded.

How to use the Compress Images for Email

  1. Drop one or more photos onto the box — Target file size is already set to 1 MB.
  2. Pick an output format if you need one (JPEG works everywhere; WebP is smaller).
  3. Each image is saved at the best quality under 1 MB. Check the before/after view, then download one image or all as a ZIP.

Where 1 MB limits come up

Email attachments are usually limited to 20–25 MB per message (Gmail, Outlook) and many company servers allow only 10 MB. At about 1 MB per photo, a dozen photos fit in one email.

How it fits the image under 1 MB

Instead of guessing a quality, the tool tries qualities and keeps the highest one that stays under 1 MB. If even low quality is too big, it reduces the width and height step by step — so text and faces stay as sharp as the limit allows. PNG images are reduced by lowering the number of colors first.

Tips

Drop all the photos at once, then use Download all (ZIP) and attach the single ZIP file.

Need a different size? Change Target file size on the page, or use the image resizer for exact pixel dimensions.

Frequently asked questions

How do I compress a photo to under 1 MB?
Drop the photo on this page — the target is already 1 MB. The tool picks the best quality that fits and you download the result. It works the same for JPG, PNG and WebP.
How many photos can I send in one email?
Gmail and Outlook allow about 20–25 MB per email. Compressed to 1 MB each, that is roughly 15–20 photos; company mail servers may allow less.
Are my photos uploaded?
No. Compression runs entirely in your browser; your images never leave your device.
Can I install Compress Images for Email as a web app and use it offline?
Yes. Compress Images for Email is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
