Use case
Images that email well
Photos straight from a phone are 5–10 MB each — that is why email with attachments crawls, times out on mobile data, or bounces outright. Compress to a sensible target below (200 KB is preselected), in your browser, with every result measured honestly.

Resize pixels (optional)
Aspect ratio is always preserved. Leave blank to keep the original pixels.

A lean email in three moves
1. Decide what the images are for. Viewed inside the message → 100–300 KB. Attached for the record → up to 1 MB. Needed for print → don’t email them at all; use a file-sharing service and compress only the web preview.
2. Cap dimensions. 1600 px wide is comfortably full-screen. Set it in the dimension limiter and let quality do the rest — this alone often halves an attachment.
3. Batch it. Drop the whole camera roll selection in at once, download the ZIP, and attach that single file. The message stays under any cap and everything arrives together.
Documents go by the same logic: a PDF letter scans beautifully at 200–400 KB — our PDF compressor handles that side, with the same no-upload guarantee.
Email size questions
How small should images be for email?
For images that appear inside the message, 100–300 KB each is plenty — they should render instantly rather than load. For attachments, keep each under 1 MB unless the recipient truly needs print quality. A Gmail message tops out at 25 MB including encoding overhead, so five 10 MB photos will not survive even one photo short of the edge case.
Should I resize dimensions instead of just compressing?
For email, yes — usually both. A photo sent for viewing does not need 4000 px width; capping around 1600 px keeps it full-screen comfortable and cuts size dramatically. The compressor has an explicit dimension limiter for this, and it respects aspect ratio.
What is the best way to send many photos?
Compress them as a batch and send the ZIP the tool produces. One attachment survives mail filters better than 20 inline images, the message stays light, and recipients unpack the originals in decent quality.
Does compressing for email require an account or upload?
No account and no upload. The compression runs in your browser, so even a photo you would rather not put on a server — a scan of an ID, medical paperwork — never leaves your device.
How do I reduce photos on my phone before emailing them?
Open the page in your phone browser, tap Choose files, pick the photo from your library, set the target and download. The compressed file lands in your downloads with its measured size in the name — no app to install.
Should I send many photos as one attachment?
Yes. Compress them as a batch and send the ZIP the tool produces. One attachment survives mail filters better than a dozen inline images, the message stays light, and the recipient still gets every photo.
