We built Zipero because file tools online were painful — pop-ups, sign-up walls, slow uploads, and questionable privacy practices. We removed all of it.
Zipero's mission is to make file conversion and processing instant, private, and free for everyone. No forced account creation for local tools. No hidden upload limits. No advertising that tracks you across the web. We believe that utility software should be straightforward: you have a file, you need it in a different format or at a smaller size, and that should take three clicks and ten seconds — not three minutes of navigating consent banners and sign-up prompts.
For the majority of Zipero's tools — PDF merging, image compression, image conversion, PDF conversion, and page extraction — all processing happens directly inside your browser using WebAssembly. Your files are never uploaded anywhere. The moment you close the tab, they are gone. For operations that genuinely require server power (video transcoding, cloud OCR), files travel over TLS-encrypted channels to our servers, are processed with priority, and are automatically and permanently deleted within 24 hours. You can also trigger immediate deletion from inside the tool itself.
We did not add privacy as an afterthought. We built it into the architecture from day one. Local tools produce zero server logs because nothing is ever transmitted. Cloud tools retain files for less than 24 hours and generate no persistent user profiles. We comply with GDPR not because we are legally obliged to (though we are), but because we genuinely believe your data belongs to you. We do not sell data, we do not build advertising profiles, and we do not use your files to train machine-learning models.
Zipero is an independent project built by a small team of developers who got tired of the existing online tool landscape. Most file conversion sites are built to maximise ad impressions, not to help users. We built the tool we wanted to use ourselves: fast, clean, honest about what it does with your files, and free for everyday use. If you use Zipero regularly and want to support the project, our Premium plan removes ads, raises file size limits, and unlocks cloud-powered tools for heavy lifting.
Zipero is built on Next.js with App Router for fast server rendering and smooth navigation. Browser-side file processing tools use WebAssembly — we compile native libraries like pdf-lib and browser-image-compression to WASM to get near-native performance without any installation. Cloud tools rely on a FastAPI (Python) backend with Celery for long asynchronous tasks, FFmpeg for video transcoding, and Tesseract for OCR. Temporary file storage uses MinIO, S3-compatible, with automatic deletion within 24 hours. Authentication is handled by Clerk. Everything is containerised via Docker Compose and deployable with a single command.
No account required for local tools — image compression, PDF merging, image conversion, and PDF conversion work without sign-up. No hidden limits: the constraints of the free tier are documented on the pricing page, not discovered at the last moment. No behavioural tracking — we do not use advertising pixels or session fingerprinting. Our analytics are limited to aggregated, anonymous metrics. Guaranteed deletion: for cloud tools, your file is automatically erased within 24 hours and immediately on request. We publish our privacy policy in plain language, not impenetrable legal jargon.
Zipero is not an all-in-one tool that promises everything and delivers little. We cover eight precise use cases — image compression, image conversion, PDF conversion, PDF merging, page extraction, video conversion, audio conversion, OCR — and we do them well. Zipero is not an application that sells you your own processing as a mandatory monthly subscription: the most common operations are free. Zipero is not a gateway to a cloud account that permanently retains your files — for local tools, your data never leaves your device.
