Compress an image to 200 KB
What this tool does
200 KB leaves the encoder enough room to keep fine detail, so this page is set up for photos you still want to look good — not just fit.
Pre-set for you: a 200 KB target file size per image. You can change it before you drop a file.
This browser cannot run the compressor. It needs Web Workers with OffscreenCanvas support, and we will not fall back to processing on the main thread because that would freeze the page. Please try a current version of Chrome, Edge, Firefox or Safari.
How this works
Your images are decoded and re-encoded inside a Web Worker in this browser tab, so the page stays responsive and the files never reach a server. There is no backend, no queue and no account.
- The original files stay on your device from start to finish.
- A target file size searches for the highest quality that fits under it, per image. If an image cannot get that small, you still get the smallest one we could make and a note saying so.
- Max width and height shrink the pixel dimensions first, which often saves more bytes than quality alone.
- Drop several images at once and the finished ones come back together in a single ZIP.
- Nothing is stored: reloading the page discards everything.
A 200 KB ceiling is the comfortable version of the same request. It leaves enough room for the encoder to keep the things photographs are made of — skin texture, foliage, fabric, fine edges — where a 100 KB budget often has to flatten them, and it still clears most upload limits with space to spare. This page arrives with 200 already in the target box.
The mechanics match every target size here: the tool searches quality settings and keeps the highest one that produces a file at or under 200 KB, then reports the setting it used. What changes at this budget is where the search tends to end. A typical photograph given 200 KB keeps a quality score in the high range, so the result reads as the original picture rather than as a compressed copy of it.
That headroom is why 200 KB is often the better choice when the file will be looked at rather than merely stored. Passport and application photos, product shots, profile pictures and anything that will be viewed at a reasonable size all benefit from the extra bytes, and the difference between 100 KB and 200 KB on a modern connection is nothing anyone will notice.
A few situations where the extra budget is wasted, and honesty about it saves you the space:
- Screenshots, diagrams, flat artwork and logos. These compress so well that they rarely approach 200 KB, and if they do, WebP or PNG will beat JPEG by a wide margin.
- Images that are already heavily optimised. Re-encoding an image that has been through a compressor once can add bytes rather than remove them, and the result panel says so when it happens.
- Anything you are about to resize anyway. Fewer pixels first, then a target size, is the order that produces the smallest file.
When 200 KB still is not enough, the lever with real power is pixel dimensions rather than quality. A 4000 pixel wide photograph will not fit into 200 KB without visible damage at any setting, but the same photograph at 1600 pixels fits easily and looks sharp at the sizes people actually view it. Drop a batch and each image gets its own 200 KB budget, with one ZIP at the end.
Frequently asked questions
Why choose 200 KB over 100 KB?
Because the extra budget is spent on detail. At 200 KB the encoder can usually keep a high quality setting, so fine texture survives; at 100 KB it often has to reduce quality enough that soft areas start to look smooth.
Is 200 KB still small enough to email?
Yes for a handful of images. If you are sending a dozen, compressing the batch here and downloading the ZIP keeps the whole attachment well inside typical mail limits.
Which format should I pick for 200 KB?
WebP by default: at the same visual quality it is usually smaller than JPEG, which means more of your 200 KB goes into the picture. Choose JPEG when the destination only accepts it.
Can I set a different target on this page?
The 200 KB figure is only a starting value, not a lock. Type another number in the target box, or clear it to let the compressor use its highest quality setting instead.
Compress Image with different settings
Drop one image or a whole batch and optionally set a target file size. The work happens inside a Web Worker in this browser tab, so your files never leave your device — and a finished batch downloads as a single ZIP.
