Frequently Asked Questions
How many images can I compress at once?
There's no hard limit! Process as many images as your browser can handle - typically 100-500 images at once depending on file sizes and your device. All processing happens locally in your browser.
Can I set different target sizes for different images?
Currently, batch compression applies the same settings to all images. For different target sizes, process images in separate batches (e.g., passport photos at 50KB, then signatures at 100KB).
What formats can I batch compress?
Upload JPG, PNG, WebP, HEIC, and most common image formats. Mix different formats in one batch - the tool handles conversions automatically and outputs optimized JPG files.
How long does it take to compress 100 images?
On a modern computer, compressing 100 images typically takes 1-3 minutes. Processing happens in parallel using your device's CPU - faster computers process quicker.
Will all images be exactly the target size?
Each image will be compressed to the target size or smaller. Some images may compress to less than the target if they're already small or have simple content.
Can I compress an entire folder at once?
Yes! Drag and drop an entire folder of images into the tool, or use the folder selection option in the file picker. All images in the folder will be processed.
Is batch compression truly free and unlimited?
Yes! Since all processing happens in your browser using your device's resources, there are no server costs or processing limits. Use it for as many images as you need, completely free.
How do I download all compressed images?
After compression, you can download all images as a single ZIP file, or download each image individually. The ZIP option is recommended for large batches.
Pro Tips
- Organize images by target size before batch processing
- Use descriptive filenames - they're preserved after compression
- Process smaller batches (50-100 images) first to verify settings
- For very large batches (500+), close other browser tabs for best performance
- Rename images with applicant names before compression for easy identification
- Test download and verify one image before processing entire batch
- Keep original images safe before batch compressing
- Use ZIP download for batches over 20 images
