Email photos without hitting the size limit
Most email services refuse a message over 20 to 25 MB, and five phone photos get you there fast. Resize them first: a photo of 1600 pixels is still perfectly sharp on a phone or laptop, but only 200 to 400 KB. That fits dozens in one email.
How to do it
- Drop your photos in the box above (up to 50 at a time).
- The settings are ready: Fit in 1600 × 1600 pixels, save as JPG, quality 80.
- Download everything as a ZIP and attach that one file, or attach the photos one by one.
A fixed limit?
If an attachment may not exceed, say, 500 KB, set the maximum file size to 500 under Advanced. The quality is then lowered step by step per photo until it fits.
Handy for WhatsApp, Signal and Teams too: smaller photos send faster and cost the recipient less data. The GPS location is removed by default, so you do not show where the photo was taken without noticing.
How it works
Three steps to resize, optimize or convert any number of images.
Upload images
Drop, paste or pick any number of JPG, PNG, WEBP, GIF, TIFF, AVIF, HEIC or SVG files.
Choose the settings
Pick a size, format and quality. Save them as a profile so they are ready next time.
Download
Every image is processed on the server, in memory. Download them one by one or all at once as a ZIP.
Features
Powered by libvips, the same engine large photo sites use. Nothing is stored, nothing goes to third parties. The demos below are live: try them.
Resize
Set a width, a height, a percentage or a box to fit in. Give one side and the other follows the aspect ratio. "Exact" forces a size and crops the rest with smart cropping.
Need the same size for a whole batch? Drop them all at once; the settings apply to every image.
Try it: change the width on the right.
Optimize
Choose a quality from 1 to 100, or set a maximum file size in KB and let the tool find the highest quality that fits. Metadata such as GPS location is stripped by default.
Lossless mode for logos and screenshots, mozjpeg for JPG, and fine control over chroma subsampling, effort and sharpening under Advanced.
Try it: drag the line and move the quality slider.
Convert
Turn anything into JPG, PNG, WEBP or AVIF, or keep the original format. The format you pick stays selected for every image you add, no surprises.
WEBP is typically 25–35% smaller than JPG at the same quality and works everywhere; AVIF is smaller still for modern sites.
Try it: pick a format and watch the file size.
Crop
Open any image from the list and drag a crop box over it, free or locked to a ratio. Social presets for Instagram, Facebook, X, LinkedIn and YouTube set both the crop and the exact output size.
The crop only applies to that one image; everything else keeps following your global settings.
Try it: drag the box or its corners, or pick a preset.
Frequently asked questions
How big can an email attachment be?
Gmail and Outlook.com allow 20 to 25 MB for the whole message, and attachments grow by about a third when sent. Keep the total under 15 MB.
How many photos fit in one email?
Resized to 1600 pixels a photo is usually 200 to 400 KB, so 30 to 50 photos fit easily in one message.
Will I see a difference after resizing?
Not on a phone or laptop. If the recipient wants to print them, send the originals through a file transfer service instead.
Does this work for WhatsApp too?
Yes. WhatsApp shrinks photos itself as well, but resizing them here first lets you choose the quality and makes sure the GPS location is gone.
