Get a high-quality photo under 1 MB — the typical limit for email attachments, forums and many upload forms. Set the target and ResizeMate compresses it to ~1 MB privately in your browser.
- Private — no upload
- No signup
- Free & unlimited
To compress an image to 1MB, upload it with the target set to 1 MB (1024 KB) and download. 1 MB keeps very high quality while meeting common email and upload limits, and nothing leaves your device.
How to compress an image to 1 MB
- Add your image. Drop in a JPG or PNG.
- Target is preset to 1 MB. Leave it, or change the number (in KB).
- Compress & download. Download your image at about 1 MB.
The limit that is really about attachments
A 1 MB target rarely comes from a form. It comes from wanting to send several photos at once without the email bouncing, or from a forum, ticketing system or messaging app that caps uploads.
Most email providers allow 20–25 MB per message in total, but that ceiling is easy to hit: ten modern phone photos at 5 MB each is 50 MB. Bringing each to 1 MB puts the whole set comfortably inside a single email with quality nobody will question.
What fits in 1 MB
| Content | Workable size | Result |
|---|---|---|
| Phone photograph | 4032×3024 | Near-original at normal viewing |
| Detailed landscape | 3840×2160 | Excellent |
| Document or receipt scan | 2480×3508 | Text stays sharp (A4 at 300 dpi) |
| Long screenshot | 1440×5000 | Clean — UI compresses well |
The target is 1024 KB. You can type any KB value if you need something different.
Sending a batch by email
If you have a folder of photos to send, compressing them one at a time is the slow way round. The bulk resizer applies one target to every file at once, and because everything runs on your own device there is no upload wait and no file-count limit.
Keep your originals. A 1 MB copy is for sending; it is not an archive, and you cannot recover the discarded detail later.
