Compress Image

What this tool does

Brings an image under the size limit you choose. UYAP does not only accept PDF — jpg, jpeg, png, tif and tiff are on the list of accepted formats too, and all of them face the same 10 MB limit. A photo of a document taken with a phone can push against that limit on its own, and Compress PDF cannot touch such a file because its input is a PDF. Quality steps are tried in turn until the file fits, and the long edge is reduced if it has to be — but only as far as it has to be.

How to use it

1. Drop one or more images.
2. Choose the limit: UYAP, email attachment, or a number of your own.
3. Compress, and read the size comparison on the result line.
4. If the file could not be brought under the limit, the tool says so plainly.

Common questions

What format does the output come in?

Always JPEG. For a photo of a document, JPEG comes out far smaller than PNG, and PNG's losslessness buys nothing on a scanned sheet of paper. The cost is transparency: transparent areas are filled with white, which on a scanned document is the colour of the paper anyway.

Can I compress a TIFF or HEIC file?

No — the tool takes JPG and PNG, and any other extension is turned away before the file even joins the list. The reason lies in the browser rather than the tool: most browsers cannot decode TIFF or HEIC, so even if such files were accepted they could not be compressed. Save the image as JPG or PNG and try again. UYAP accepting TIFF does not change this: handing it a JPG is just as valid.

What happens if the image is already under the limit?

The file is left as it is, and the result line says so. Re-encoding an already well-compressed JPEG usually makes it bigger; when its own output is larger than the original, the tool hands back the original.

What if it cannot get under the limit?

You still get the result from the lowest step, but the result line says the limit was not reached. When that happens the image itself is simply too large — rescanning the page at a lower resolution, or retaking the photo, gives a better result than pushing further.

Are my files uploaded anywhere?

No. The image is decoded in your tab, drawn to a canvas and re-encoded there; at no point does it leave your machine.
