Any files · zipped on your device, nothing is uploaded
No size limit · files are processed on your device and never uploaded · how it works
Advanced settings (optional)
Compression
Level
The sensible default.
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the Create ZIP
Drop any files — documents, images, a whole project.
Pick a compression level (Normal suits almost everything).
Create the ZIP and download one tidy archive.
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
One attachment instead of forty
Email limits, upload forms that accept a single file, sending a folder's worth of scans — zipping is still the universal
answer, and it does not need installed software. Files are read and packed in your browser; the archive appears as a
download, and nothing is transmitted anywhere.
Compression, honestly
ZIP shrinks text, spreadsheets and code dramatically — and photos, videos and MP3s barely at all, because those are
already compressed. For media, the value is one file instead of many; choose Store and it packs instantly. Need the
photos themselves smaller? Run them through the image compressor first.
Frequently asked questions
Which compression level should I pick?
Normal, almost always. Store (no compression) is instant and right when the files are already compressed — photos, videos, MP3s barely shrink. Max squeezes text and documents hardest at the cost of speed.
Why is my ZIP of photos barely smaller?
JPGs and PNGs are already compressed; ZIP cannot squeeze them further. The value of the archive is one attachment instead of forty, not a smaller total.
Is there a limit?
No fixed limit — your device’s memory is the ceiling.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
