Optimize your workflow with these batch processing tips.
Batch processing works best when images are similar in size and format. Group your images by type before processing for more predictable results.
Before processing 100+ images, test your settings on a small batch of 5. Verify the output quality, then run the full batch with confidence.
When converting for websites, choose WebP format. It produces 25-35% smaller files than JPG at equivalent quality — a huge win for page load speed.
Always keep a backup of your original images. Batch processing overwrites settings — if the results aren't right, you'll want the originals to try again.
Batch processing 100+ images uses significant memory. Close unnecessary tabs and apps to give the browser maximum resources for faster processing.
Before batch processing, rename your files with a consistent pattern. The ZIP download preserves filenames, so good naming keeps everything organized.
No uploads. No tracking. No compromises. Your images never leave your device.
