Compress Image to 240 KB
Compress an image to 240 KB or less in your browser — free, unlimited, and your file never leaves your device.
No account · No daily limit · No card · Nothing to cancel
Full pixel size keptRe-encodes only if the file gets smaller Nothing is ever made bigger
The encoder works at a quality that does not show, and stops there. You do not pick a number.Your images are processed by your own browser. Nothing is uploaded, there is no account, and there is no daily limit.
Compress to another size
Every limit is different. These run on the same engine, so switching is instant.
What 240 KB leaves alone
240 KB suits a picture that has to carry two subjects at once: the front and back of an ID card photographed side by side, a document with a signature and a photograph on the same page, or a form whose image the instructions say to scan together.
Two regions mean roughly twice the detail of a simple portrait, so a size in the low hundreds of kilobytes is the right budget rather than 50 or 100 KB.
When a form allows 240 KB
- Both sides of an identity document in a single image
- A page that must show a photograph and a signature together
- Forms that ask for one scan instead of two uploads
- Any picture where the reader must be able to read text and see a face
Caps in the hundreds of kilobytes
Once a limit reaches the hundreds of kilobytes it has stopped being about saving space and started being about keeping uploads sane. Advertising portals, print shops and listing sites use this range because it comfortably holds a detailed photograph while still being small enough to move around a network without thought. In practice you will often not need the tool at all here — plenty of camera photos arrive under 350 KB on their own. When you do need it, the change is one careful re-encode rather than a squeeze.
How a file at 240 KB looks
Enough for two legible regions if you keep the pixel dimensions. Cutting the dimensions to hit the size is what makes the second region unreadable.
A file that lands here usually keeps its original pixel dimensions and looks like the original at any normal viewing size. If your source is already under the target, the honest answer is that there is nothing to gain and the tool will say so instead of re-encoding for the sake of it.
How it works
- Add your imageDrop it above, or choose a file from your device.
- Choose howSmallest file keeps the best quality and takes no number, or set the exact size your form asks for. Nothing is compressed until you press Compress.
- Compress and downloadPress Compress, and the finished size is shown before you save, so there are no surprises.
Questions
How do I compress an image to 240 KB?
Drop your image into the box above, check that the target reads 240 KB, and press Compress. The finished size is shown before you download, so you can see that it fits before you save it.
Will 240 KB change how my photo looks?
Barely. At this size the encoder can usually keep the full pixel dimensions and still fit inside the limit, so what changes is the file, not the picture.
Is 240 KB enough for a photo I might print?
For a small print, yes; for a large one, be careful. Printing magnifies the fine detail that compression removes first, so if you plan to print, a target in megabytes is the safer choice.
Will compressing to 240 KB ruin the quality?
Enough for two legible regions if you keep the pixel dimensions. Cutting the dimensions to hit the size is what makes the second region unreadable.
Can I fit two things in one 240 KB image?
Yes, and this is a common reason to pick it: an ID card photographed front and back side by side, or a document with two pages in one frame. A wider image at 240 KB stays readable, where the same file at 100 KB would not.
Which format should I choose — JPG, PNG or WebP?
Photos: JPG or WebP, because they are built for photographs. Logos, signatures, screenshots and anything with flat colour: PNG, so the sharp edges stay sharp. If you are not sure, leave it on “keep original format”.
What does “240 KB or less” mean here?
The tool aims just below your number, never above it. If the image is already smaller than 240 KB it is left untouched rather than re-encoded and degraded.
Is this free? What is the catch?
There isn’t one. The compression runs inside your browser using technology already built in, so there is no server doing the work and nothing to charge for. This page shows ads, and that is the whole business model.
