How to compress images without overdoing it
For photos, quality between 70 and 85 often gives a good balance between size and appearance. WebP can be smaller than JPG in many browsers, while JPG remains widely compatible for uploads and older workflows.
Veelgestelde vragen
Can this compress PNG files?
You can upload PNG files, but the compressed output is JPG or WebP because those formats support quality-based file reduction.
Is mijn afbeelding geüpload?
No. Your image stays in your browser and compression runs locally.
Why use max width?
Large camera photos often have more pixels than needed. Reducing width can lower file size more than quality changes alone.
