Choosing the right image format when scanning or photographing physical documents significantly influences the speed and accuracy of subsequent OCR text extraction.
JPG (JPEG) employs lossy DCT compression, making it exceptionally lightweight for sharing multi-page batches. However, high compression ratios can introduce blocky artifacts around sharp character edges, occasionally confusing OCR engines with small typography or accented glyphs.
PNG utilizes lossless DEFLATE compression, preserving pixel-perfect sharpness around text glyphs and diagrams. While file sizes are larger than JPG, PNG is the gold standard for high-accuracy OCR on contracts, technical manuals, and archival paperwork.
WebP provides modern algorithmic efficiency, supporting both lossy and lossless modes with up to 30% smaller sizes than comparable JPGs while preserving text contrast. Our converter natively handles all three formats seamlessly in-browser.
