Lighter files.Easier work.
PubToo compresses and extracts many kinds of files: images, PDFs, video and audio, plus packing and unpacking files and folders — all in one app. Shrink files before you send them, save space when you store them, and tidy things up when you archive them.

Images & PDFs
Compress images by quality, target size or reduction, and convert between JPEG, HEIC, WebP, AVIF and more. Compressed PDFs keep working text and links.
Audio & video
Export video as H.264 or HEVC MP4, optionally at 1080p or 720p. Convert audio to AAC, or losslessly to ALAC or FLAC.
Files & folders
Pack files and folders into ZIP or 7z with an optional password, and extract ZIP, 7z, RAR, TAR and other common archives.
About Zinuto
Small frictionsdeserve real solutions.
Not every problem is dramatic, but small interruptions add up. A file is too large to send. A document gets overwritten and earlier edits are gone. We build software so these everyday moments have a better tool.
We don’t cram every feature into one app or chase the same technology with every product. We start from a specific need and make each solution clearer, smoother and more trustworthy.
Our Chinese name, 轻创掘金, pairs two ideas: solving problems with clarity and restraint, and finding what’s worth building in real needs.
Leave complexity to tools.Leave possibility to people.
We want useful software to fit naturally into everyday life, so people spend less time on repetition and more on creating and focusing. The value of technology should show up in every easier moment.
