Batch Conversion FAQ

Common questions about converting multiple images at once.

How many images can I batch convert at once?+
There is no hard limit. Because processing happens in your browser, performance depends on your device. Most modern computers handle 50-100 images with ease. For very large batches, we recommend processing in groups of 50.
Can I mix different input formats in one batch?+
Yes! You can select HEIC, JPG, PNG, WebP, AVIF, GIF, BMP, and TIFF files all in the same batch. Every image will be converted to your chosen target format with the same quality settings.
Will batch conversion slow down my computer?+
The converter is designed to use your CPU efficiently without freezing your browser. Processing is handled in Web Workers, so you can continue using other tabs while your images are being converted.
Is there a file size limit?+
There are no artificial file size limits. Since everything runs in your browser, the practical limit depends on your device's available memory. Files up to 50 MB each work well on most devices.
