You choose the file
The browser can access files you explicitly select or drop. This does not grant the site permission to scan your entire hard drive.
LOCAL-FIRST COMPUTING · ZORYVIA
Your files stay. Your device does the work.
We send tools and algorithms to your browser, instead of sending your files to our servers. Select, process on your device, then download your result.
Not an upload-then-download cloud converter
For Zoryvia file tools marked local processing, selected file contents are read and transformed inside your browser—not uploaded to a Zoryvia processing server. Your browser still downloads the website and its processing code.
Your device runs the work
Text and PDF generally use CPU; images use Canvas; WebGPU and hardware video codecs are used only when supported. Not every tool uses a GPU.
You keep the result
The browser creates a local download. File processing uses your CPU/GPU, memory and temporary storage, subject to device and browser limits.
What the pledge actually means
How can I check there was no upload?
Open Developer Tools → Network, choose your file and run the tool. Inspect outbound requests for file contents. We also run regression tests against unintended file uploads. Loading JavaScript, CSS or website resources is not uploading your file.
Are all Zoryvia services local?
No. PDF, image, text and local video tools are designed for on-device execution. Public website diagnostics must perform network checks on the domain you enter; Support receives only information you explicitly submit.
Can every browser use the entire GPU?
No. Browsers expose sandboxed APIs. WebGPU, WebCodecs and hardware codecs vary by browser, operating system and format. Unsupported devices get an explanation, not a silent cloud upload.
Does this guarantee perfect security?
No service can guarantee zero risk. Browsers, extensions, operating systems and website code require ongoing maintenance. Our concrete pledge for local file tools is no upload of selected file contents, backed by code review and network tests.
What could we charge for?
These tools are currently free and checkout is not live. Future paid options may cover advanced algorithms, automated workflows, batch processing, templates and support—not resale of your CPU/GPU resources.
Your device, our tools.
