How ConvertCraft runs your jobs

For normal files, we run as much as possible directly in your browser using WebAssembly (FFmpeg, PDF tools, etc.). That’s why ConvertCraft often feels snappy — no long uploads, no background tracking.

For very heavy files, browser limits still exist. During the Alpha, Pro improves limits but stays browser-first. In the future, Pro will add dedicated server engines for monster jobs.

ConvertCraft Pro is in Alpha: you get higher limits and an ad-free lab, but we’re transparent that some multi-GB and extra-complex jobs will only arrive once our server engine is online.

What is ConvertCraft and why is it different?

ConvertCraft is a file lab designed for creators, students and power users. Many tools run directly in your browser for speed and privacy, with Pro reserved for bigger jobs and extra comfort.

Browser-first, not server-first

Where other sites upload every file to their servers, ConvertCraft tries to run conversions right on your device using WebAssembly. That means less waiting, no hidden tracking pixels and more control.

Privacy by design

For tools that run locally, your files never leave your browser. When a server helper is needed, we’ll tell you clearly which tools use it and how long files are kept.

Built for real use: creators, gamers, students

Discord avatars, TikTok/Shorts presets, student PDF tools, audio and video utilities — ConvertCraft focuses on the jobs you actually do every week, not random formats you never touch.

Global, not just English

ConvertCraft ships with many languages, including RTL support. We want you to feel at home whether you’re using English, Arabic, Turkish or other locales.

Privacy FAQ

Do files leave my device?

Most conversions run entirely in your browser. If a helper server is needed, files are encrypted in transit and auto-deleted within minutes.

How long are files stored?

When a server fallback is triggered (for example PDF rasterization), temporary artifacts are purged shortly after the job completes.

Who can access my data?

Only your browser handles the data by default. We never build user profiles and analytics are aggregated once you grant consent.

How big can my files be?

Free limits: up to 100 MB images, 250 MB videos, and 50 MB audio. ConvertCraft Pro and the Day Pass unlock background workers that comfortably handle multi-gigabyte videos and archives.

Do you keep my files?

No. Browser conversions never leave your device. When a helper server is required, the file is encrypted in transit, stored briefly for processing, and auto-deleted minutes after the job finishes.

Does it work on mobile?

Yes. The UI is touch-friendly and works on iOS Safari, Android Chrome, and modern mobile browsers. Very large jobs may pause if the tab sleeps, so keep the screen awake for faster exports.

Will EXIF/metadata be removed?

Image and video conversions strip EXIF and other metadata by default to minimize file size. Use the “Keep metadata” toggle inside advanced settings if you need to preserve it.

What if a conversion fails?

Retry after refreshing the page, close other heavy tabs to free RAM, or switch to the helper server fallback (for PDFs) if available. If it keeps failing, email [email protected] with the file type and browser so we can reproduce it.
