Frequently Asked Questions
Is this image converter really free?
Yes, 100% free with no hidden costs. Unlike other tools, we don't require registration, don't add watermarks, and don't limit how many images you can convert. This tool is offered free as part of our mission to make basic image tools accessible to everyone.
What's the maximum file size I can convert?
You can upload images up to 20MB in size. This is sufficient for most high-resolution photos and graphics. For larger files, consider using our Image Compressor tool first to reduce the file size.
Are my images stored on your servers?
No. Your images are processed in real-time and immediately discarded after conversion. We don't store, view, or share your images. Your privacy is fully protected.
Which format should I choose for my website?
For most websites, WebP is the best choice - it offers excellent compression with wide browser support (97%+ globally). For the smallest files, consider AVIF, though check your audience's browser support first. Use JPG as a fallback for maximum compatibility.
Will converting my image reduce its quality?
It depends on the conversion. Converting to PNG is lossless (no quality loss). Converting to JPG, WebP, or AVIF involves compression - use higher quality settings (80-100%) to minimize quality loss. Converting from a lossy format to another lossy format may accumulate quality loss.
Can I convert multiple images at once?
Currently, our tool converts one image at a time for optimal quality control. For batch conversions, you can quickly convert multiple images by uploading them sequentially - our instant processing makes this fast and efficient.
What's the difference between WebP and AVIF?
Both are modern formats with excellent compression. AVIF typically achieves 20-30% smaller files than WebP at the same quality, but takes longer to encode. WebP has broader software support, while AVIF is newer but supported in all major browsers. Choose WebP for compatibility, AVIF for maximum compression.
Why can't I open my converted AVIF/WebP file?
Some older software doesn't support modern formats. If you need to open AVIF or WebP in older applications, convert them to PNG or JPG first. Most software released after 2020 supports WebP, and 2022+ generally supports AVIF.
