Common questions about image conversion
Which image format should I choose?
The choice depends on the use case. JPEG is best for photographs and images with smooth gradients. PNG is the right choice when you need transparency or lossless storage. WebP gives the smallest file size with good quality and is supported in all modern browsers.
- Web pages: WebP (smallest file size, best performance)
- Photos for email or social media: JPEG (universal support)
- Graphics with transparency: PNG or WebP
- Print and further editing: PNG (lossless)
How do I convert images without quality loss?
Lossless conversion is possible between certain formats. Conversion to PNG is always lossless regardless of source format. Conversion to JPEG or WebP involves lossy compression, but at quality 0.92+ the difference is barely visible.
- PNG to PNG: completely lossless (format change only)
- WebP to PNG: lossless — all pixels preserved exactly
- PNG to JPEG: some loss, choose quality 0.92+ for best results
- Each re-conversion via JPEG adds loss — avoid converting back and forth
Is it safe to convert images in the browser?
Yes. Bildconverter processes all images locally using the browser's Canvas API. No files are uploaded to any server. Your images never leave your computer, making it safe to handle sensitive images.
- All processing happens in your browser with JavaScript
- No data is sent over the network (verify in browser network tab)
- The tool works offline after the first load
- Only exception: if you enter a URL, the image is fetched via a proxy
How do I remove GPS and metadata before sharing images?
Go to the Edit tab, check "Remove EXIF metadata" and click Apply. The image is recreated via canvas without embedded metadata. Use the Inspect tab first if you want to see what information exists.
- All EXIF, GPS, IPTC, XMP and ICC metadata is removed
- The image is redrawn — visually identical but without hidden information
- Verify by uploading the result in the Inspect tab
Can I convert multiple images at once?
Yes. Upload multiple files by selecting them in the file picker or drag and drop a group. All are converted with the same settings. Download individually or as ZIP.
- Drag and drop multiple files at once
- All images are processed in parallel in the browser
- Click "Download all (ZIP)" for a combined download
Image format comparison
| Format | Transparency | Compression | Typical file size | Best for |
