How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
60 KB is a common weight for pictures placed inside an email or a newsletter. Mail clients load them over whatever connection the reader has, and a light picture appears before the reader scrolls past.
The tool works through quality settings and keeps the best one that stays at or under 60,000 bytes. A large original is scaled down as well, since an email column is seldom wider than 600 pixels.
Email images are read on phones more than on desktops now. A 60 KB picture at 600 pixels wide displays crisply on a small screen and does not eat the reader's data.
Email widths and file weight
Newsletter templates usually run about 600 pixels wide. At that width 60 KB is 480,000 bits, which gives roughly 0.8 bits per pixel for a 600 by 800 portrait. That is enough for a clean photo with a calm background.
Why inline pictures matter
Many mail clients block images until the reader allows them. When they do load, a heavy picture can leave a blank gap for seconds. Keeping each one around 60 KB means the whole message fills in almost at once.
Text inside images
A banner with words baked into the picture needs a different approach from a photo. JPEG at 60 KB can leave halos around letters. Try WebP or PNG for banners with text and see whether the edges stay crisp.
Also remember that some mail clients show no image at all, so the message should still make sense as plain text.
Previews and attachments
If you attach pictures rather than embedding them, the limit that matters is the total size of the message. Compressing each attachment to 60 KB lets you send a dozen of them and stay far below the usual mailbox limits.
Retina screens and email
Phones with sharp screens show a 600 pixel image blurry if it is displayed at 300 points. Send the picture at its full 600 pixels and let the email template shrink it by setting the width. The extra pixels cost little at 60 KB and show as sharper detail.
Do not scale it up past the pixels you have, since stretching only enlarges the blur.
Dark mode and transparent backgrounds
Some readers view email in dark mode, where a white box around a logo shows up as an ugly rectangle. If your picture has a transparent background, save it as PNG so the box disappears. A JPEG always has a solid background.
If any picture feels slow, lower its target and make a new version.
Dark mode and transparent backgrounds
Some readers use dark mode, where a white box around a logo shows as an ugly rectangle. When your picture has a transparent background, save it as PNG and the box disappears. A JPEG always carries a solid background.
With PNG, watch the weight, which climbs fast for photographs.
Frequently asked questions
Is 60 KB right for a newsletter hero image?
For a 600 pixel banner, yes. A full-bleed hero may need 100 KB or more to stay sharp.
Will Outlook and Gmail display the result?
JPEG, PNG and GIF display everywhere. WebP is accepted by most modern clients but not all, so JPEG is the cautious choice.
Can I compress an animated GIF here?
This page handles still images. Animated GIFs have their own compressor.
How do I check the final size?
The result row shows it in kilobytes next to the new dimensions.
Does a transparent PNG fit in 60 KB?
Often yes, when the picture is simple and not very large. Reduce the width if it does not fit.
