Fast tools for urgent file problems
Last reviewed: August 3, 2026
FileChak handles the file problems that appear just before an upload: image size limits, exact dimensions, scanned document photos, PDFs and Korean HWP documents.
What makes it different?
Instead of listing generic editing features, FileChak builds workflows around specific outcomes such as 100KB limits, exact pixels, conversion checks and privacy-safe copies.
File-processing principle
Standard file tools process the selected files in the current browser and do not upload the originals to FileChak servers.
Editorial standard
Guides describe steps the product actually provides and show their review date and publisher. Destination rules can change, so users are reminded to check the latest official requirement before submission.
