Frequently Asked Questions
What image formats are supported?
The converter supports JPG (JPEG), PNG, WebP, and AVIF formats. You can convert from any supported format to any supported output format.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device.
What does the quality slider do?
The quality slider controls the compression level for lossy formats (JPG, WebP, AVIF). Higher values produce larger files with better visual quality. PNG is lossless and ignores this setting.
Can I convert multiple images at once?
Yes, you can select and convert multiple images in a single batch. All images will be converted using the same format and quality settings.
Which format should I use?
Use JPG for photos (smallest file size). Use PNG for graphics with transparency. Use WebP for the best compression-to-quality ratio. Use AVIF for next-gen compression.
Does quality affect file size?
Yes. Higher quality produces larger files. For web use, 80-90% quality offers a good balance between file size and visual quality.
