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.
Free · Unlimited single images, free Nothing uploaded · no account · works with Wi-Fi off
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.
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.

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.

Like the tool? Own it.
The free page resizes unlimited single images. The €9 Batch Image Resizer download is the same tool as a single file: whole folders in, one zip out, no daily limit, offline forever. One-time payment — no subscription.
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 unlimited single images, one at a time. The €9 download batch-processes any number and gives you one zip — no limits, offline forever.
