Use a format converter when a destination requires JPG, PNG or WebP, including HEIC-to-image workflows. Use dedicated JPG or PNG compression when the output format itself must stay unchanged, and use Crop or Resize when the real requirement is image geometry.

Many workflows combine steps: crop to the right composition, resize to the display dimensions, then compress; or convert to a compatible format before optimizing the result.

Image tools that solve one task each

Toolmera keeps each image page focused on a real task: format compatibility, output quality, transparency, palette reduction, crop geometry or pixel dimensions.

FAQ

Common questions about image tools

Should I resize or compress an image first?

If the image dimensions are much larger than the final display size, resize first and compress afterward. Reducing unnecessary pixels usually creates a better final file-size result.

Can I make a JPG smaller without converting it to another format?

Yes. Compress JPG keeps the output as JPG and gives you a quality control plus a before-and-after file-size comparison.

Which image format should I use for transparency?

PNG and WebP can preserve transparent areas. JPG cannot, so transparent pixels need to be replaced with a solid background when exporting to JPG.

Do Toolmera image tools upload my files?

The current image conversion, crop, resize and compression workflows process files locally in the browser.
