Browser-local processing

File privacy

For tools marked Browser Local, the image-processing path stays inside the browser tab. The website supplies code; your device performs the conversion.

The local path

You select a file, the browser reads it into temporary memory, a local processor creates a new Blob, and the page generates a temporary object URL for preview or download.

  • File selected on your device
  • Decoded by browser APIs
  • Processed in the current tab
  • Result held as a temporary Blob
  • Downloaded through a local object URL

What does not happen

Released browser-local tools do not send the image to a PicConverters conversion server. There is no server request containing the selected file bytes, filename, EXIF, or generated output.

03

Temporary memory and object URLs

Object URLs are browser references to local in-memory data. PicConverters revokes them when results are cleared or the component closes. Refreshing or closing the page ends the current session and clears in-memory workflow transfers.

04

Browser-loaded codecs

Future specialist tools may download codec code and run it locally. Those tools will be labeled Browser + Codec. Loading a codec is different from uploading your image; the file still remains on the device unless a tool explicitly declares otherwise.

05

Your responsibilities

Keep originals, review results, avoid processing files on an untrusted device, and clear browser data when using a shared computer. Browser-local architecture reduces transfer risk but does not secure the device itself.
