ToolnozaJPG and PNG serve different purposes
JPG uses lossy compression and is often practical for photographs or smaller email attachments. Each re-save can reduce quality, and JPG does not preserve transparency. PNG uses lossless compression, which suits text, diagrams and crisp interface graphics, but its files may be larger.
Neither format preserves selectable PDF text, links or form fields as an image. If those features matter, share the PDF instead of exporting page images.
Choose resolution before converting pages
PDF-to-image resolution is usually set in dots per inch (DPI). Higher DPI creates more pixels and can increase file size; it does not add detail that was absent from the source. For a screen preview, a moderate setting is often enough. For print, consider the image’s final physical size and the printer’s requirements.
Convert only the pages you need, choose JPG for photos or PNG for sharp text and graphics, then inspect small type at the intended display size. Toolnoza exports selected pages as image files in a ZIP; check the download before sending it.
Frequently asked questions
Will a PNG always be clearer? It avoids JPG-style lossy compression but can still look soft if the source PDF is low resolution. Can I turn the images back into editable text? Not reliably; OCR is a separate process and may make recognition errors. Why is the ZIP large? High DPI and PNG images can produce many pixels and larger files.
