Processed in this browserCore file processing runs on this device; the work files do not need to be uploaded to FileNest first.
File contents are not uploadedWork files stay on this device for this tool; outputs are generated or downloaded within the browser workflow.
Service metadata ≠ file copiesSigned-in features may store account, quota, job, download or saved-rule records; those records do not contain copies of your work files.

FAQ
Questions before you begin
When does the free quota return?
Each successful file drops out of the count 24 hours later. You do not need to wait until midnight.
Do failed files use quota?
No. A file counts only after the browser successfully creates its result.
Are images uploaded?
No. Conversion, crop and compression run in this browser. Use the separate local image OCR tool when you need to extract text.
Use the existing image workspace when a set of files needs one consistent output format. Add the batch, choose JPG, PNG or WebP, review quality and generated files, then download without uploading the source images.
PNG to JPG: check transparency first
Use JPG when transparency is not required. Preview the result before batch download so transparent PNG backgrounds do not become an unexpected output.
JPG to WebP for web delivery
Convert suitable JPG website assets to WebP in one batch, then inspect the generated file size and visual result rather than relying on a promised saving percentage.
WebP to PNG when a PNG workflow requires it
Convert WebP files to PNG when downstream software or delivery rules require PNG. Format conversion does not create image detail that was absent from the source.
Illustrative workflow: choose the output format for the real task and inspect the result. No fixed compression saving is promised; this is not a live conversion screenshot.
