for email
Photos that actually attach
Gmail, iCloud, Outlook — every email host caps attachments somewhere between 20 and 25 MB. A handful of phone photos blows through that fast. Compress at 75% JPG, attach the same shots, send in one go.

Smaller photos, same look.
Drop a photo, pick a format, slide the quality. Watch the file shrink — usually 60–90% smaller with no visible difference. JPG, WebP, or lossless PNG. Nothing uploads anywhere; the encoder runs on your device. For real projects, grab a proper app.

where smaller files actually help
Six places compression earns its keep
for web uploads
Squarespace, Shopify, Etsy, WordPress
Most CMS platforms warn (or silently downgrade) anything over a few MB. Compress to 1920px WebP at 75 before uploading — your gallery loads quicker, Lighthouse scores climb, and you skip their auto-conversion step.
for blog posts
Pages that load before readers leave
A single 6 MB header image is the single biggest reason a blog post feels slow. Resize to 1200px and re-encode WebP at 70 and the same image weighs ~120 KB — same look, fifty times lighter.
for messaging
WhatsApp, iMessage, Slack
Messaging apps re-compress everything you send anyway, often badly. Pre-compress to JPG 75 at 1600px first — you control the quality, the recipient gets a sharper photo, and you don't burn through someone's mobile data.
for print
Hit the kiosk file-size limit
Walgreens and CVS print kiosks limit individual file size on USB upload. A 12-megapixel iPhone shot is sometimes too big. Compress at 90% JPG (still print-grade) and you're under the limit without losing visible quality.
for the archive
Free up the family photo drive
10 years of phone photos add up. Re-encode the archive to WebP at 80, keep originals only for hero shots — you'll cut total size in half without anyone noticing the difference on a screen or a print.
in case you're wondering
Frequently asked
Does my photo upload anywhere? +
No. The encoder runs in your browser tab using the canvas API. Your photo never touches our servers — we don't run an image pipeline at all. Open DevTools → Network and watch: nothing leaves your device.
What's the difference between JPG and WebP? +
WebP is a newer format that gets ~25–35% smaller than JPG at the same visual quality. Every modern browser, email client, and CMS supports it now. JPG is still the safest pick for printing, kiosks, and forwarding to people on old devices.
When should I pick PNG? +
Only when you need lossless — diagrams, screenshots with text, anything you'll edit again later. PNG is much larger than JPG/WebP for photos and the quality slider doesn't apply.
What's the right quality setting? +
75 for JPG and 70 for WebP are the sweet spots for the web — visually indistinguishable from the original on a phone or laptop. Push to 90+ if the photo is going to print or large displays. Below 60, banding and JPEG artifacts start to show.
Why does resizing matter so much? +
A modern phone shoots 4000–8000px wide. Almost no screen is bigger than 2400px. Resizing to 1920px before compressing cuts the file in half before quality even comes into play. Resize first, compress second.
Can I batch a folder of photos? +
Single-photo for now — the tool is built for quick, one-off compression. For batches of 50+ photos, a desktop app or a build script (sharp, ImageMagick) is the right tool.
