All Tools →About Convertilo
Convertilo brings into a single tab what is usually scattered across many websites. Compress photos, merge PDFs, translate text with a neural network, format JSON, calculate percentages and loans — no context switching.
Files are never uploaded to our server: WASM codecs compress images, pdf-lib processes PDFs, text and speech recognition run through WebAssembly — all right in your browser. No sign-up anywhere.
Why Convertilo
No server, no signup
Files and text are not sent to our server. No accounts, limits or hidden fees.
Works offline
After the first page load tools keep working without internet — codecs and the neural network are cached in your browser.
All in one tab
Images, PDFs, translator, calculators — dozens of tools instead of a dozen different sites.
FAQ
How much does Convertilo cost?
It's completely free. No signup, no file limits, no watermarks, no hidden charges.
Where are my files uploaded?
Nowhere. Every tool runs locally in your browser through WebAssembly codecs. Files are never sent to our servers or stored anywhere outside your device.
Does it work on mobile?
Yes, every tool is tuned for mobile browsers. A Telegram Mini App is also available for quick access directly from the messenger.
Which image formats are supported?
JPG, PNG, WebP, AVIF, HEIC, GIF and SVG. Conversion works both ways for most format pairs, and compression and resizing work for all of them.
Can I work with PDFs without installing anything?
Yes. Merging, splitting, compressing, converting to images and signing are all available directly in the browser — PDF files never leave your device.
What is Convertilo?
Convertilo is a collection of free online tools for working with images, PDFs, documents, translations and calculators. Images, PDFs and recognition run right in your browser via WebAssembly, and files are not uploaded to our server. No sign-up anywhere.
Is it safe to upload confidential documents?
Yes. Images, PDFs and text are processed locally in your browser — we never receive the files themselves and don't store the results. This matters for contracts, medical records, personal photos and legal documents.
How does Convertilo differ from Smallpdf, iLovePDF, Convertio?
The key difference is privacy. Most online services upload your file to their servers for processing. Convertilo uses WebAssembly and neural networks right in the browser: the document never leaves your device. Plus — no limits, no registration, no subscriptions.
How much does it cost?
Free. No subscriptions, no file-size limits, no operation caps. All tools available without registration.
Which languages does the translator support?
16 languages: English, Russian, Ukrainian, German, French, Spanish, Italian, Polish, Czech, Portuguese and more. Translation is done by a neural model that weighs the context of the whole phrase, so idioms are rendered by meaning rather than word for word.
