• Processing runs in your browser—files and text are not uploaded to Apex Toolz servers for storage.
• Related tools in the pdf category appear below—chain tasks without re-uploading elsewhere.
• Unlock password-protected PDFs in the source app before merge, split, or compress.

• Very large files may stress browser memory—split batches on low-RAM devices.
• Always verify platform rule changes on official docs—presets approximate common specs.
• Common mistake — skipping spot-check on the first file in a batch: confirm settings on one sample before queueing hundreds.
