US Letter and ISO A4 mismatch causes cropped footers when European PDFs print on American copiers, and vice versa. Resizing standardizes dimensions before mass printing or portal upload without rebuilding the source file in Word.

Siliph Resize PDF scales content proportionally in the browser-backed engine with encrypted uploads. Choose preset paper sizes or enter millimeter dimensions for niche label stock and architectural sheets.

Proportional scaling preserves aspect ratio on charts and photos, avoiding the squashed look that comes from stretching one axis only. Vector text remains selectable when the source was digital-born.

Auto-deletion within two hours on the free tier limits retention risk, and resizing works without signup. Pair with Crop PDF when you must remove margins after scaling to a smaller sheet.

For image-only scans, Compress PDF afterward if the resized raster pages grew file size; for forms, verify field alignment after aggressive size changes.

Siliph edit utilities—crop, rotate, headers, Bates numbers, metadata—apply changes in the browser with encrypted handling from the moment you drop a file. Finished PDFs auto-delete within two hours on the free plan, and every edit workflow opens without signup.
