## What is PubToo Go?

PubToo Go compresses images, PDFs, video and audio, and creates, browses and extracts ZIP and 7z archives. Everything is processed on your device, with no account and no uploads.

Images
Pick from Photos or Files and compression starts as soon as they are imported. Work by quality, by percentage or toward an exact file size, resize along the way, and convert between JPEG, PNG, HEIC, WebP, AVIF and GIF. Compare before and after, then save to Photos or Files, or share the result with another app. Location and camera details are removed from exported images.

PDF, video and audio
PDFs can be optimized losslessly, balanced, or made as small as possible. Video is re-encoded as H.264 for compatibility or HEVC for smaller files, at the original resolution, 1080p or 720p. Audio exports as AAC, or stays lossless as ALAC or FLAC. Each can also work toward a target size.

Archives
Create ZIP or 7z archives, with a password when you need one. 7z archives can also encrypt file names and be split into volumes. Protected archives open with their password, and each archive extracts into its own folder.

Details
