Frequently Asked Questions
How many images can I batch resize at once?
PDFtiny has no hard limit on batch image count. You can upload and process 50, 100, or more images simultaneously. Processing time scales with image count and your device speed.
Can I resize images to different dimensions per image in a batch?
The batch resizer applies the same dimensions or percentage to all uploaded images. For different dimensions per image, process each image individually using the Image Resizer tool.
What formats can I resize in bulk?
JPG, PNG, and WebP are fully supported for batch resizing. HEIC images should first be converted to JPG using the Image Converter, then batch resized.
How do I download all the batch-resized images?
After batch processing, click "Download All as ZIP" to receive all resized images in a single compressed archive. Individual downloads are also available for each image.
