Common Conversions (and When to Use Them)

Converting re-draws each image on a canvas, so camera EXIF data (including GPS location) is not copied into the new file. If you only want to strip metadata without changing format, use the EXIF remover. Converting to WebP or AVIF often shrinks files, but if you need a specific target size, run the result through the compressor as well.

Frequently Asked Questions (FAQ)

Q: How do I convert an image to WebP or JPG online?

A: Upload one or more images, choose the output format (JPG, PNG, WebP, AVIF, or GIF), convert, then download files individually or as a zip. No account needed.

Q: Can I convert multiple images at once?

A: Yes. This free image converter supports batch conversion of up to 20 images (10MB each) and can package results as a zip download.

Q: Which format should I use: JPG, PNG, or WebP?

A: JPG is great for photos. PNG is better for logos, transparency, and sharp edges. WebP often gives smaller files with strong quality for the modern web. AVIF can be even smaller but with less universal support. GIF fits simple animations.

Q: Is the image converter free?

A: Yes. Convert images online for free with no registration, install, or watermark.

Q: Does the image converter upload my photos?

A: No. Decoding and conversion run in your browser with HTML canvas, so your images are not uploaded to QuickImgTools servers. The zip file is also built on your device.

Q: Will converting change image quality?

A: Converting between lossy formats (like JPG/WebP/AVIF) can introduce compression differences. PNG is lossless. Pick the format that matches your use case and preview results when quality matters.

Q: What happens to transparency when I convert PNG to JPG?

A: JPG does not support transparency, so transparent areas are filled with white. To keep a transparent background, convert to PNG or WebP instead.

Q: Can I use iPhone HEIC or AVIF photos?

A: Yes. Add iPhone HEIC/HEIF or AVIF files directly — they decode in your browser (no upload, no convert-first step) and convert to JPG, PNG, or WebP in the same batch. AVIF output depends on browser support; if your browser cannot encode AVIF, the file is saved as PNG and labeled honestly. Re-encoding drops HEIC metadata such as GPS location. (HEIC-only batches? HEIC to JPG has resize options.)

Q: Does converting make my images smaller?

A: Often, but not always. PNG to JPG or WebP usually shrinks photos a lot, while JPG to PNG makes files larger because PNG is lossless. The results table shows the size change for every file. For tighter control, compress the result with the free image compressor or reduce dimensions with the resizer.
