Image formats and what each one does
Timamu Web compresses JPEG, PNG, WebP and AVIF images. The format decides how the file shrinks. JPEG, WebP and AVIF are lossy, so a smaller file gives up some fine detail. PNG is lossless, which suits screenshots, logos and anything with text or sharp edges, but a photo saved as PNG is usually much larger than the same photo as JPEG, WebP or AVIF.
Steps to compress an image
- Open Timamu Web and choose the image, or drop it onto the page.
- Pick a mode: Protect Quality keeps the look, Reach Target works toward a size you enter, and Smallest Possible goes as far as a valid file allows.
- Run the job. When a target is set, Timamu reports the requested and the actual size.
- Download the prepared copy. The original is never replaced.
Format-specific gotchas
- JPEG loses a little detail every time it is saved. Compress from the original photo, not from a copy that was already compressed.
- A PNG with transparency cannot become a JPEG without losing the transparent area. Timamu does not flatten it silently.
- Animated WebP is not preserved. Timamu stops instead of keeping only one frame.
- AVIF is limited to standard 8-bit colour. HDR AVIF files are declined.
- A very large photo can be declined when the device cannot hold it in memory. The original stays untouched either way.
Questions
Which format gives the smallest photo?
For photographs, AVIF and WebP usually give smaller files than JPEG at a similar look. JPEG opens almost everywhere, so it is the safer choice when the destination is unknown.
How do I shrink a screenshot without blurring the text?
Keep the screenshot as PNG and use Protect Quality. Converting a screenshot to JPEG makes it smaller but can smear small lettering.
Why did my image barely change size?
Images that were already exported at a low quality setting have little left to remove. Timamu keeps the result valid and reports the size it reached.
