Compress Image to 100 KB

A hundred kilobytes suits most forums, job boards and CMS attachments. The target is already on; pick a file and press apply.

A hundred kilobytes is the everyday budget: forum attachments, job application portals and CMS uploads commonly stop there. This panel opens with that target in place, measures each attempt against it, and shows the true size in the Result figure. For JPEG and WebP, the search spends quality before it spends pixels.

Drop a file in; the 100 KB target is already active.
Adjust nothing else unless the picture needs a different mode.
Press Apply Compression and let the search finish.
Read Result and Saved, then download from the header.

What the options do

Target File Size: One hundred kilobytes is preselected. For JPEG and WebP, the panel looks from the ceiling downward for the highest quality that still fits, and makes the image smaller only when the floor itself fails.
When a hundred KB is too tight: Rather than gut the picture, the tool returns the best file that stays above the floor and says the target was missed, with the real size printed underneath.

The number the site quoted is the number to type here: upload, apply, compare Result against 100 KB, and download if it passes. If it lands over, a slightly lower quality ceiling or a modest dimension trim usually closes the gap.

Common questions

Is 100 KB enough for a photo?: Often, yes — a typical JPEG lands near that range after a careful search. Dense detail such as foliage or small text is what pushes a file upward, so those pictures have the least room to give.
Can I undo a compression I regret?: Yes. Every apply is one history step, so Undo in the workspace header returns the previous version, and Reset to original brings back the upload unchanged.
Does the target apply to PNG files?: It is accepted and measured, never chased: PNG is lossless, so reaching a byte count would mean discarding pixels. The panel reports the size it really produced and points you at JPEG or WebP when the ceiling matters.
