Worked example: a listing photo for an email application
A 4000-pixel camera JPG may be 3–6 MB. Set JPG or WebP, keep 200 KB, and compress. Check the result dimensions. If the portal also wants a minimum width, use the 200 KB file only when that width still holds; otherwise raise the target or send a link instead of forcing more compression.
What this job is for
Email systems count the encoded attachment, which is a little larger than the file on disk. Aiming at 200 KB with a result slightly below that leaves a buffer. Do not zip a JPG unless the recipient asked for a zip; that rarely helps a single photo.
Useful limits
For a multi-image email, compress each photo separately from the master files. Repeatedly opening and saving the same download stacks artefacts.
The live tool behind this page is Image Compressor. It is the same local engine as the rest of Image Cosmos.
Frequently asked questions
Why not exactly 200 KB?
Encoders pick a quality table, not a byte slider. The tool searches for the best result that stays under the target.
Should I use 200 KB or 100 KB for email?
Use the limit the host states. If none is stated, 200 KB is a practical single-photo attachment; 100 KB is safer for several images in one message.
Does Image Cosmos send the photo?
No. The attachment you download is created locally.
