Common File Conversion Questions Answered

Quick answers to the file conversion questions that show up over and over in r/learnprogramming, r/techsupport, r/SoftwareRecs, and the various office-app subs. Each links to a deeper guide where the answer needs more space.

Office documents to plain text

What’s the best way to convert Office documents to plain text?

Three quick options:

1. Word / Google Docs: File → Save As → Plain Text (.txt). Loses all formatting; preserves text content.
2. Pandoc CLI: pandoc -o output.txt input.docx. Best for batch — preserves headings as Markdown-style markers if you use --to=markdown instead.
3. For sensitive content: use LibreOffice headless (libreoffice --headless --convert-to txt *.docx), no cloud round-trip.

Strip-formatting tip: paste the formatted text into a plain-text editor first, then re-paste into the destination. Removes all hidden styles, colors, fonts. Works for transferring text between web apps that have been fighting your formatting.

Metadata + privacy

How do I convert files without losing metadata?

Format-by-format. JPEG/HEIC/TIFF: most converters preserve EXIF on simple format changes — verify the output. PDF: preserved across PDF↔PDF, lost on conversion to images. DOCX: preserved on DOCX↔ODT, lost on PDF export unless explicitly enabled. Plain text + CSV + JSON have no metadata support — embed in content if needed. See our quality preservation guide for the full breakdown.

How do I strip metadata from a PDF before sharing?

Use our PDF metadata remover. Browser-only, removes title / author / subject / keywords / creation date / producer fields. Good for any document you’re publishing where the metadata reveals something you don’t want shared (internal author names, draft history, machine names).

How do I see what metadata is in a PDF?

Use our PDF metadata viewer. Browser-only, shows all standard PDF metadata fields plus XMP if present. Useful before sharing — you’ll see exactly what would leak.

Graphics format choices

What’s the best file converter for graphics?

Depends on the conversion. PNG/JPG/WebP/AVIF: our image format converter handles all of them in browser. HEIC: HEIC to JPG. SVG to raster: SVG to PNG with resolution slider. For batch image work: ImageMagick CLI. For pro photo editing: Photoshop or GIMP.

What’s the difference between PNG, JPG, and SVG?

JPG: lossy compression for photos. PNG: lossless with transparency, for screenshots and line art. SVG: vector format, infinite resolution, for logos and icons. JPG/PNG are pixel-based; SVG is math-based. Detailed comparison in our file formats guide.

Speed + size questions

How do I convert files faster?

Five tips: keep the conversion tab in foreground, close other tabs, use lower-quality settings if pristine output isn’t needed, process in batches with re-used engine (FFmpeg, Pandoc), skip unnecessary intermediate steps. Detailed breakdown in our troubleshooting guide.

Does file size matter for conversion speed?

Yes — but it’s linear or worse. Browser tabs cap at 2-4 GB memory. Files over 500 MB push browser-only tools to limits. Switch to desktop tools (FFmpeg, ImageMagick, Pandoc, LibreOffice headless) for gigabyte-scale files.

Why do some file conversions take so long?

Five factors: file size, source format complexity (multi-column PDFs slower than text-only), conversion type (lossless reformat is fast, reflow + restructure is slow), browser-side vs cloud (cloud has GPUs), OCR is always slow at 5-15 seconds per page. See the troubleshooting guide for the full diagnostic flow.

Rare formats + edge cases

Can you convert encrypted files?

With the password / key, yes. Without it, no — encryption is designed to prevent reading without the key. DRM-protected media (Kindle KFX, Audible AAX) is illegal to circumvent in most jurisdictions. Lost own passwords sometimes recoverable via vendor support (Microsoft account recovery, Adobe). Otherwise plan to live without or reconstruct.

Can I convert between rare file formats?

Almost always, with patience. Check if the format has a published spec (most do — ISO, RFC, vendor whitepapers). Search GitHub for parsers. For binary formats, format research sites like Format Wiki sometimes have field-by-field breakdowns. Last resort: hire a freelancer specialized in data-format work — $100-500 per file. Detailed in our behind-the-scenes guide.

What file converter myths should I ignore?

Multiple conversions don’t always damage quality (only lossy chains do). PDFs don’t always lose quality on edit. AI-powered converters are mostly marketing — exception is OCR. Free CLI tools often outperform paid SaaS on speed. Larger output files don’t mean higher quality. Full myth-busting in our behind-the-scenes guide.
