When to use this tool
Switch between JPG, PNG, and WebP formats when a platform, app, or workflow requires a specific file type — for example, uploading a PNG to a form that only accepts JPG, or converting a batch of photos to WebP for a faster website.
Quality tips
- Converting from a lossy format (JPG, WebP) to a lossless one (PNG) keeps the same quality — it cannot restore detail that was already discarded by the source compression.
- For JPG output, a quality setting of 85–90 % is a reliable starting point that balances visible quality and file size for most photos.
- When converting PNG to JPG, transparency is replaced with a solid background (white by default) — preview the result if your original has transparent areas.
Common mistakes
- Expecting quality to improve when converting from a lossy to a lossless format — the sourceʼs compression artifacts remain.
- Not checking whether the output format supports the features you need, such as alpha transparency (PNG, WebP) or CMYK (JPG only, and limited).
- Using maximum quality (100 %) for every JPG output — the file is often 2–3 × larger than at 90 % with no visible difference on screen.
