Frequently asked questions
- Are my images uploaded?
- No. Every tool runs in your browser using standard web APIs, so your image files are processed on your own device and are not uploaded to ImageTidy or stored anywhere.
- Is ImageTidy free?
- Yes. Single-image resizing, compressing and converting are free, with a fair-use allowance of 10 image operations per rolling 24 hours and no account required. Premium removes that limit and unlocks bulk processing.
- What image formats are supported?
- JPG/JPEG, PNG and WebP for both input and output. Support depends on the image encoders built into your browser, and all current major browsers handle these three formats.
- Can I use ImageTidy on my phone?
- Yes. The site works on phones and tablets. Very large images use more memory on mobile, so on older devices it helps to work with a few files at a time.
- Do I need to install anything?
- No. There is nothing to download or install. A modern web browser is all you need, and there is no account or sign-up.
- How does image compression work?
- JPG and WebP use lossy compression: a quality setting decides how much fine detail is discarded to make the file smaller, so lower quality means a smaller file and more visible artefacts. PNG is lossless — it is re-encoded without discarding detail, so savings are smaller and depend on the image.
- Does ImageTidy support bulk resizing?
- Yes. Bulk Resize processes many images at once with shared dimensions and format settings and hands you a ZIP file. It runs in your browser like the other tools, and it is a Premium feature.
