Keeping documents readable
For scans of certificates or ID cards, text sharpness matters more than colour. Photograph the document flat, fill the frame, and avoid shadows. After compressing, open the result at full size to confirm the text is still readable; if it is not, use a higher limit when the form allows it.
Before you upload
- The output is always JPG, and transparent areas turn white. If the form requires PDF or PNG, this tool is not suitable.
- The tool only enforces the 100 KB upper limit. If the form also sets a minimum size, check the file size in the result.
- Maximum width and height are optional. The image keeps its proportions, fits inside that box and is never enlarged or cropped. If the form needs exact dimensions, check the size shown in the result.
- If the tool says it cannot reach 100 KB, crop the image first and try again. More detail is in the how-to guide and FAQ.
If you have several pages, compress each image separately – the tool handles up to 20 files at once and names each download with the target size.
