Email-ready in one step
A sensible default of 1280×720 at good quality turns an unsendable camera photo into a clean attachment that clears every major provider.

Features
Hit an exact server limit
Stuck behind a strict 10 MB or 5 MB corporate cap? Switch to KB-target mode, type the limit, and the file lands underneath it.
Private and instant
The photo is resized in your browser and stays on your device. No wait, no signup, and nothing of yours sitting on someone's server.
Resize a photo for email in three steps
Drop your photo
Drag the image in, tap to pick it on your phone, or paste from the clipboard. HEIC shots straight off an iPhone are welcome.
Pick an email size
Tap the email-friendly preset, or type your own dimensions, or set an exact KB cap. The estimated attachment size updates as you go.
Download and attach
Save the smaller copy and attach it to your message. Your original full-resolution photo stays untouched on your device.
Common email-resize jobs
Send holiday photos to family
A dozen full-resolution snaps will bounce as one message. Resize them all to 1280×720 and the whole set attaches comfortably, still looking great on a laptop or phone screen.
Attach a photo to a work email
Corporate servers are stingy with attachment size. Drop your image, set the KB cap your IT team enforces, and send without the message getting rejected on the way out.
Email a product or listing photo
Selling something? Buyers want to see it, not wait for a 12 MB download. A 1600-pixel-wide JPG looks crisp in the email and arrives instantly.
Submit a photo to a teacher or course
Assignment portals and instructors often want a single emailed image under a few MB. Resize to fit the limit while keeping the detail that matters legible.
Send a photo to an insurer or landlord
Claims and maintenance requests need clear photos that actually send. Shrink each shot to an email-friendly size so the whole report goes through in one message.
Email a receipt or document scan
Scans are large and rarely need full resolution to stay readable. Resize to a modest width so the text is clear and the attachment is light.
Why your photo will not send — and how to fix it
Email was never built to move large files. Gmail caps attachments at 25 MB, Outlook.com at 20 MB, and many corporate servers draw the line lower still, around 10 MB. Modern phone photos routinely blow past those limits — a single high-resolution shot can be 10 to 15 MB on its own, and a few of them together bounce the whole message.
The fix is almost always to resize, not to compress harder. A photo at 4000×3000 pixels has far more detail than anyone reading it in an inbox will ever see. Pull it down to around 1280×720 and the file collapses from megabytes to a few hundred KB while still looking sharp in the recipient's preview pane. AnyResizer does this in one step, with an email-friendly default already dialed in.
Everything runs in your browser, so the photo never leaves your device. It just gets smaller and attaches normally. Need to hit a specific server limit? Switch to KB-target mode, type the cap your IT department enforces, and the output lands inside it. Sending several photos? Resize them all at once and attach the batch.

Tips for emailing images
- Tip 1:
1280×720 at JPG quality 80 is a reliable all-purpose email target: it previews cleanly, inline-renders in most clients, and stays a few hundred KB.
- Tip 2:
Total message size counts, not just one file. If you are attaching several photos, resize every one — a handful of 2 MB images still adds up past the limit.
- Tip 3:
When a recipient needs to print or zoom, say so and send a link to the full-resolution file instead of forcing it through email.
- Tip 4:
For a hard server cap, use KB-target mode rather than guessing dimensions — it lands inside the limit without trial and error.
- Tip 5:
Sending an iPhone photo to a Windows user? Convert HEIC to JPG on the way out so it opens everywhere without a plugin.
Resize image for email FAQ
What size should an image be to email it?
For most messages, around 1280×720 pixels at JPG quality 80 is ideal — a few hundred KB that looks sharp in any preview pane. Go larger only when the recipient genuinely needs to zoom or print.
What is the attachment limit for Gmail and Outlook?
Gmail allows up to 25 MB per message, Outlook.com up to 20 MB, and Yahoo around 25 MB. Many corporate mail servers enforce lower limits, often 10 MB or less, which is why resizing first is the safe move.
How do I make a photo small enough to email?
Drop it here, tap the email-friendly preset or type a smaller width, and download. If you need to meet an exact cap, switch to KB-target mode and type the limit.
Will the recipient still see a clear photo?
Yes. Email is viewed on screens, and a 1280×720 image already exceeds what most preview panes display. The resize removes detail nobody was going to see, not detail that matters.
Is my photo uploaded anywhere when I resize it?
No. The resize happens in your browser with WebAssembly, so the image never leaves your device. You then attach the smaller copy to your email as usual.
Can I resize an iPhone HEIC photo to email it?
Yes. Drop the HEIC and it is decoded instantly. Resize it and convert to JPG on the way out so it opens for everyone, including Windows recipients.
Can I email several resized photos at once?
Yes. Drop all of them, apply one email-friendly size, and download the set. Remember the total message size is what counts against the limit.
Should I resize or compress for email?
Usually resize. Photos carry far more pixels than an inbox needs, so reducing dimensions does most of the work. Compression can shave a little more afterward if you are right at the edge of a limit.
