What is a File Converter?
A file converter changes a file’s format to improve compatibility, quality, or size. Common examples include converting images for the web (PNG → WebP), preparing print-ready documents (JPG/PNG → PDF), or extracting visuals from documents (PDF → JPG/PNG/TIFF/WebP).
Good converters balance quality and size, preserve transparency where applicable (PNG/WebP), and keep layout for PDFs (page size, margins, fit-to-page). Our tools expose sensible defaults so most users can convert in seconds.
Lossy vs. Lossless, Raster vs. Vector
- Lossy vs. Lossless: JPG/WebP (lossy) shrink size by discarding some data; PNG/TIFF (lossless) keep full detail. Choose lossy for web sharing, lossless for editing/archival.
- Raster vs. Vector: JPG/PNG/WebP/TIFF are raster (pixels). SVG/AI are vector (shapes, paths). Raster needs adequate resolution (DPI) for print; vector scales infinitely without blur.
- Color & Metadata: Conversions can affect ICC profiles, EXIF, or alpha channels. Our image-to-PDF tools preserve transparency behavior appropriately and fit images to page with margins for predictable print.
Popular Conversion Categories

How It Works
- Pick the converter for your exact format pair (e.g., PNG → PDF).
- Upload one or multiple files (batch supported on many tools).
- Click convert — defaults are optimized for quality and size.
- Download your result instantly. No sign-up, no watermarks.
Tips: Keep image aspect ratios consistent when merging to PDF for a uniform layout. For web, consider WebP to reduce size with excellent quality.
Security & Privacy
- Encrypted Transfers: Files move over secure connections.
- Auto-Deletion: Processed files are deleted automatically.
- No Permanent Storage: We do not keep your files after processing.
- No Watermarks: Results are clean and ready to use.
- It changes a file from one format to another (e.g., JPG → PNG, PDF → JPG) to improve compatibility, quality, or size.
- PDF ↔ Image (PDF → JPG/PNG/WebP/TIFF and JPG/PNG/WebP/TIFF → PDF) and Image ↔ Image (JPG ↔ PNG, PNG ↔ WebP) are the most used.
- Yes, lossy formats like JPG/WebP reduce size with adjustable quality; lossless formats like PNG/TIFF preserve detail.
- PNG and WebP support alpha channels. When converting to PDF, pages are laid out with margins and fit-to-page behavior for predictable output.
- OCR is not enabled by default. For text extraction from images/PDFs, use dedicated OCR tools.
- Most converters support up to 100MB per conversion. For larger files, split or compress first.
- No. Files are processed securely and auto-deleted after conversion.
- Many tools support multi-file upload and merging (e.g., Merge JPG → PDF, Combine PNG → PDF).
Note: Each converter is optimized for a single format pair, ensuring the best quality and speed. For the most uniform PDF layout, use consistent image dimensions and orientation.
