What to check

Actual size and quality depend on your image. Settings do not certify acceptance by another service.
How to use this guidance
- 01
Choose your original
Select an image and keep a copy. Animated GIF input produces a still image.
- 02
Set a maximum and dimensions
Enter the destination’s requirements. Custom dimensions remain fixed even when a very small cap cannot be reached.
- 03
Inspect the output
Check actual bytes, pixels and readability. A preset does not guarantee third-party acceptance.
PNG can preserve transparency. Canvas PNG export does not use a lossy quality slider; meeting a small cap can require fewer pixels.
With custom dimensions fixed, the PNG may remain above your target. Check the actual result or choose a different format when the destination permits it.
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.
