If you need a bespoke version

You can keep using this free tool as it is. If you need a bespoke version with your own rules, data or workflows for a website, shop or internal process, I can build it for you – for example with custom rules and data sources, approvals and exports, and website or shop integration.

Smaller images without sending them away

Large image files slow down websites, fill inboxes and use unnecessary mobile data. The image workshop therefore works in two ways: it reduces the pixel dimensions and saves the result again with suitable compression.

WebP, JPG, PNG or AVIF?

  • WebP is a good default choice for photos and graphics on the web.
  • JPG is suitable for photos when the result needs to open in as many programs as possible.
  • PNG preserves transparent areas and sharp graphics, but often creates larger files.
  • AVIF can produce particularly small files. This output is available only when your browser can create AVIF itself.

What happens to metadata

The image is rebuilt on a new browser canvas. EXIF data, camera model, capture time and stored GPS coordinates are not included in the new file.

Frequently asked questions

Are my images uploaded?
No. The website loads only the program code. Your images are then read, processed and made available for download again in your browser on your device.
Why does an image sometimes become larger?
PNG and very high quality settings can create files larger than the original. Choose WebP or JPG for photos and reduce the quality gradually.
Does this work on a mobile phone?
Yes. With very large or numerous images, a phone may reach its memory limit more quickly. Process a smaller selection in each batch in that case.

How to use this tool

Compress and convert images and remove embedded metadata.

  1. Select one or more images.

  2. Choose the file format, quality and, when needed, a maximum image size.

  3. The results appear automatically. Compare them with the originals and download individual images or all of them as a ZIP.

Terms used in this tool

Pixel dimensions
The width and height of an image in pixels, for example 2,000 × 1,500 pixels.
Image quality
The strength of lossy compression. A higher setting preserves more detail but usually creates larger files.
Metadata
Additional information in an image file, such as camera model, capture time or location.
