Why your image still exceeds an upload limit

Read the complete upload requirement

An upload form may specify both a byte limit and dimensions. An image can be below 100 KB yet fail because its width is wrong. Write down the accepted file types, maximum size, and required dimensions before changing your file.

Put this guide into practice with the Image Compressor. Review the tool’s inputs, example and limitations alongside your result.

Remove what you do not need

Crop empty space first. A photograph of a small signature in the middle of a large sheet spends pixels on the sheet. Crop & Rotate Image lets you choose a tighter rectangle, but you should retain all content the receiving service requires.

Reduce dimensions before forcing extreme compression

A large photograph cannot always remain clear under a tiny byte budget. Resize to the destination dimensions, then use Image Compressor. Its target-size mode adjusts quality and may reduce dimensions further if quality alone cannot meet the limit. Check that the final dimensions are still acceptable.

Choose an accepted format

JPEG suits many photographs. PNG preserves transparency but is not always small for a photograph. WebP can be useful when the receiving site accepts it. Changing a filename extension does not convert the file.

Inspect, then upload

Check the downloaded size and preview. ToolMallow uses 1 KB = 1024 bytes; a destination may count differently. If an exact limit fails, leave a small size margin. Do not sacrifice readable document details just to get a smaller number.
