Try a fresh export first. Damaged, partial, encrypted, split, or unusually large ZIP archives may fail integrity checks and should not be silently processed.

10 focused guides for this part of the WhatsApp-to-PDF workflow.
WhatsApp Chat Export Has the Wrong Dates
Ambiguous dates such as 04/05 can mean different things in different regions. A converter should detect the ambiguity, let you choose day/month or month/day, and require a preview check.
Read guide →Why WhatsApp Messages Are Out of Order in a PDF
The PDF should follow transcript order rather than re-sorting by sender or file modification time. If timestamps cannot be parsed, those entries should stay in source order and be flagged.
Read guide →WhatsApp PDF Shows Missing Photo Placeholders
A placeholder means the transcript referenced an image but the matching file was unavailable or ambiguous. Re-export with media or select the missing image file together with the TXT.
Read guide →WhatsApp Export Is Too Large to Convert
Reduce the scope: export without media, select a shorter period for the final PDF, or divide the job into smaller conversation segments. Very large media archives can exceed browser memory limits.
Read guide →Why a WhatsApp TXT File Has Strange Characters
Character issues usually come from text encoding or damaged exports. Modern WhatsApp exports are Unicode; a converter should reject unreadable encoding rather than replacing lots of characters silently.
Read guide →Why a WhatsApp Export Has Multiple TXT Files
A ZIP can contain attached text documents as well as the chat transcript. If several files look like conversations, unzip the archive and choose the correct chat TXT with its media rather than guessing.
Read guide →Why a WhatsApp PDF Is Blank
A blank result usually means no messages were parsed, the selected date range excludes everything, or the browser could not render the document. Recheck the source file and preview counts before download.
Read guide →Why WhatsApp File Upload Does Not Work in a Preview Viewer
Embedded document viewers may block file pickers, JavaScript, downloads, or browser APIs. Open the actual website in Safari, Chrome, Edge, or Firefox rather than an attachment preview.
Read guide →How to Fix a WhatsApp PDF With the Wrong Time Format
Keep the clock value from the export and avoid timezone conversion unless the tool clearly explains it. If the source contains 12-hour or 24-hour times, the PDF should display them consistently.
