How PDF pages become images
A PDF page is not simply an image file. Toolmera uses a PDF rendering engine in the browser to paint the selected page onto Canvas, then exports those rendered pixels as JPG or PNG.
Choose JPG for compact photographic-style output or PNG when you want a lossless image encoding of the rendered page.
Page selection and render scale
Enter all to render every page, or use page syntax such as 1-3, 5. The render-scale control changes the pixel dimensions produced from the PDF viewport.
Higher scale gives more pixels and sharper small text, but it also increases output size, rendering time and browser memory use.
Multi-page downloads and limitations
A single selected page downloads as one image. Multiple selected pages are processed sequentially and bundled into a ZIP file.
Password-protected PDFs are not supported in the current version. Very large or complex PDFs can also be limited by available browser memory.
