Frequently asked questions
How many images can I process at once?+
Up to 50 images per batch. Each image can be processed into multiple sizes simultaneously — for example, 10 images × 4 preset sizes = 40 output files in one ZIP download.
Why is my PNG file size not reduced in batch mode?+
PNG is a lossless format and cannot be compressed via quality adjustment. In batch mode, use "Target size" with JPEG or WebP format for actual compression. Leave it as "None" to simply resize or convert without compression.
How are the output files named?+
Each output file is named: original-name_size-label_dimensions.ext (e.g. "sunset_Instagram_Square_1080x1080.jpg"). All files are bundled into a single ZIP archive for easy download.
Do I need to select both a format and a size?+
No. You can just compress (select a target size), just resize (select preset or custom sizes), or both. If nothing is selected, the images are output at original size in the chosen format.
