How to use this guidance

  1. 01

    Choose your original

    Select an image and keep a copy. Animated GIF input produces a still image.

  2. 02

    Set a maximum and dimensions

    Enter the destination’s requirements. Custom dimensions remain fixed even when a very small cap cannot be reached.

  3. 03

    Inspect the output

    Check actual bytes, pixels and readability. A preset does not guarantee third-party acceptance.

Crop unused margins without cutting signature strokes. Enter dimensions and the permitted file range from your form.

The 140 × 60 px / 15 KB preset is an illustrative setting. It is not a rule for every examination or application.

Common questions

Does a target guarantee an exact file size?

No. The target is a requested maximum. Inspect the actual bytes, dimensions and visual quality; a very small target can remain unmet.

Will compression keep every detail?

JPEG and WebP can lose detail. PNG uses lossless encoding, but resizing changes pixels. Keep your original and compare the preview.

Does this tool set print DPI metadata?

DPI converts centimeters or inches to pixels. This browser export does not write your chosen print-DPI tag. Check pixel dimensions and use print software for physical print settings.
