Why this exact limit matters
Two hundred kilobytes is the attachment budget of the well-behaved email: a single photo at 200 KB sails through every gateway, and even a message with five of them stays under the strictest corporate limits. Unlike portals, mail systems enforce nothing per attachment — they simply fail the whole message when the total crosses their line, which makes every photo’s size your problem.
Shrinking attachments to a stated size keeps mail deliverable without forcing you to learn a photo editor just to send a picture. 200 KB is a moderate limit, common for application portals, and this page is preset to exactly that ceiling.
How to compress to 200 KB
- Drop your image into the box above — it stays on your device.
- Confirm the target: under 200 KB as JPEG.
- The MozJPEG encoder searches its quality range so the JPEG output lands just under your limit. Dimensions are left at their original size unless the target demands otherwise.
- Preview the result, compare it with the original if you want, and download — the filename carries its actual size.
Tip: If you attach photos regularly, compress before attaching rather than relying on the mail client's "large attachments" link — those links expire, while a small attachment is a real attachment.

Quality 34 at full frame is the "keep everything, pay in quality" route — fine for a photo that will be viewed at inbox size. The alternative measured on the same file: a 1920-pixel cap at this ceiling holds quality 65. For email, where nobody zooms past display size, the capped version is usually the better trade.
Frequently asked questions
How many 200 KB photos can I attach before gateways complain?
Practical limits sit at 10–25 MB per message, so dozens fit — but recipient mailboxes render messages with many large images sluggishly. For photo-heavy messages, 5–8 attachments at this size is the comfortable ceiling.
Does re-encoding strip the photo’s location metadata?
Yes — the output is a fresh JPEG without the original EXIF, including GPS coordinates your phone embedded. For email that is almost always desirable; mention it if the recipient needs the geodata.
The recipient says my photo looks blurry — was it the compression?
At quality 34 full-frame, mild softness is visible when zoomed. Re-send with a 1200-pixel cap and the same 200 KB ceiling: fewer pixels, higher quality, sharper at the size people actually view.
Does compressing remove the photo's EXIF data like location?
Re-encoding replaces the original metadata, which means location and camera information from the source file is not carried into the output — usually desirable for attachments.
Why JPEG and not another format for my upload?
JPEG is the most universally accepted image format on upload forms and gives the smallest files for photographs. If your destination accepts only "images", JPEG is the safe choice.
Do I need an account or app install?
No account, no install, no watermark. The page you are on is the whole tool.
