How to use
Select up to 20 images, choose JPEG or WebP and quality, then download the real encoded files in a ZIP.
Limits and behavior
Lossy re-encoding may increase some file sizes. At most 80 MB input, 16 million decoded pixels and 64 MB output. Still PNG, JPEG and WebP only; 20 MB, 4 megapixels and 4,096 pixels per side. Processing stays on your device. Exports apply orientation and discard source metadata. PNG output preserves transparency unless the selected operation composites it.
Bulk photo and image compression
Compress multiple images together using a selected lossy quality level. This batch image compressor is useful for preparing photo collections, web graphics or image attachments without adjusting every file separately.
Does bulk image compression change quality?
Yes, lossy re-encoding can reduce detail. Compare the outputs with the originals and keep backups when the source images are important.
