A practical starting point

Make a photo smaller before uploading

Reduce a photo’s file size with a JPEG export, compare the result with the original, and check the destination’s size and format requirements.

3 steps to get startedSources reviewed
The existing image compressor exports one image as a JPEG with adjustable quality. You can inspect the file-size change and download the result; it is not a batch or transparent-image exporter.

A practical way forward

  1. Check the upload requirements

    Note the allowed format and maximum file size. Keep your original photo, and use a different workflow if the image needs transparency or animation.

  2. Adjust and compare

    Load one photo, lower JPEG quality gradually and inspect important details such as small text, edges and faces. Compare the output size instead of assuming every export is smaller.

  3. Try the actual destination

    Download the JPEG, reopen it and confirm dimensions and appearance. Test that the receiving form accepts it before processing other photos.

Keep in mind

  • The current output is JPEG; transparency and animation are not preserved.
  • Large images can use substantial browser memory, and an export may be larger than its source.

Batch images to a target size

Research only — not available yet. Would a queue of images with per-file size targets save a repeated upload-preparation task?

All solutions

Resize an image without stretching it

Calculate proportional image dimensions, decide whether to crop or fit, and check the final asset at the size where people will actually see it.

Check colors before using them in an interface

Convert a color value for your stylesheet, check its contrast against the actual background, and avoid using color alone to communicate meaning.
