Photos too big to email? Shrink them — free, without uploading
Every email client has an attachment limit — Gmail and Outlook cap out at 25 MB, and a handful of modern phone photos eat that before you've attached five. Here's how to shrink photos to email size in one pass, free, without uploading them anywhere.
Why your photos are so big
A modern phone photo is roughly 4000×3000 pixels at 3–5 MB. That's enough resolution to print a poster — and completely wasted on an email that will be read on a screen maybe 500 pixels wide. The recipient's mail app doesn't need 12 million pixels; it needs a photo that looks sharp and loads instantly.
The 60-second fix
- Open the free batch image resizer.
- Drop in the photos you want to send.
- Set fit to max 1600 px (width and height), quality 85%. Keep "Prevent upscale" on so nothing small gets enlarged.
- Download the zip and attach the shrunken files. A dozen photos now weigh about 2–3 MB total — comfortably inside any attachment limit.
Everything happens in your browser: no upload, no account, no watermark. Go offline after loading the page and it still works.
What size should email photos be?
| Goal | Max dimension | Result |
|---|
| Quick snapshot to a friend | 1200 px | ~150 KB each, looks fine on phones |
| Photos people might want to keep | 1600 px | ~250 KB each, sharp on any screen — the safe default |
| Someone will print them | don't shrink — send a link to the originals or use the download tool's full-size pass |
Three habits that keep inboxes happy
- Resize once, keep the original. Shrink a copy for sending; the full-resolution files stay untouched in your folder. Future-you may want to print them.
- Zip when it's many. One zip of shrunken photos beats 20 individual attachments — and this tool hands you the zip.
- Huge set? Send a link instead. Beyond ~10 photos, a shared folder link is kinder to both inboxes. Shrink only the few that truly must be attached.

Questions people ask
How small will my photos get?
Typically 10–15×: a 4 MB phone photo at 4000×3000 becomes a ~250–350 KB JPG at 1600 px and quality 85% — visually indistinguishable on a screen.
Will the recipient see a quality difference?
Not on any screen. 1600 px at quality 85% is sharper than most monitors display. Only large prints would reveal the difference — and for those, keep the original.
Do my photos get uploaded anywhere?
No. The resizing runs entirely inside the page — no server, no account, no network calls. Works with your Wi-Fi off.
Can I shrink a whole folder at once?
The free page handles 3 images a day so you can try it properly. The €9 download batch-processes any number and gives you one zip — no limits, offline forever.
