Three tasks for a file you need to submit
The home page focuses on fitting a photo to a file-size limit, combining scanned photos into one PDF, and keeping the PDF pages you need. Choose a task and continue through file selection, settings, processing and saving on the same page.
Destinations set their own format, size and page requirements. This service helps prepare the file; it does not certify a document or guarantee acceptance. Keep the original and reopen the file you saved before submitting it.
Original files and real outputs explain the choices
Our file experiments publish synthetic sources, actual output files, exact byte counts and processing conditions. You can check when PNG to JPG makes a file larger, how image-PDF resolution affects small text, and what information remains after metadata removal.
Each measurement belongs to the published sample and conditions. It does not guarantee the same size or quality for another file. We distinguish instructions from measured observations and make source and output files available together.
Privacy by architecture
Supported conversions run on the device whenever the tool displays the private browser processing notice. Files are not sent to our server or third-party conversion APIs.
Supported browser processing
Each tool page lists its accepted formats and current limitations. Results depend on the browser decoder, available memory and the source-file variant; review displayed warnings and verify important downloads in a trusted application.
Existing tools and separately operated services
The full catalog retains the existing image, HWP/HWPX, PDF, audio and video tools. HWP and HWPX conversion creates a visual PDF for review and does not retain editable or searchable document structure.
JUUD Apps also operates Lotto Record as a separate service for historical drawing records and probability interpretation. It is not part of the file-preparation workflow.
Operation and hosting
JUUD File Tools is operated by JUUD Apps, and its public pages are delivered through Cloudflare. Supported file conversions run in the current browser; source files are not sent to the hosting provider as conversion inputs.
