📂 Batch Upload Rule
For multi-file uploads, all files in the same batch should use the same source type (for example all JPG or all MP3).
PDF (Portable Document Format) is a fixed-layout document format for sharing and printing. JPG (Joint Photographic Experts Group) is a compressed photo format. Try our Universal Converter for other file formats.
Quick rules and tips to get the best results.
For multi-file uploads, all files in the same batch should use the same source type (for example all JPG or all MP3).
Set your preferred output quality to balance file size and clarity. Compression behavior is tailored to each file format.
Each conversion request supports up to 200 MB total. Each user can upload a total of 500 MB per hour.
Completed jobs are saved on this device for up to 1 hour, unless you remove them from the list.
Converting PDF to JPG turns each PDF page into an image you can preview, share, or embed quickly. Text and graphics are rendered into pixels first, then encoded with the selected quality setting. Higher quality usually keeps edges and small text cleaner, while lower quality makes smaller files for easier transfer. This route works well when you need visual page snapshots rather than an editable document.
For PDF sources, each page is rasterized and exported as image output, so multi-page files can produce multiple images in one run. This keeps page order predictable for review, markup, and visual sharing workflows.
In PDF to JPG conversion, quality mainly controls how aggressively the output is compressed. Key parameters are fixed 200 DPI (dots per inch) rasterization, per-page pixel rendering, and the destination image encoder. After rendering, quality tunes encoder compression strength (for example JPEG/WebP quantization or PNG compress-level behavior). Page geometry is decided first, so quality changes mostly affect edge sharpness, artifacting, and output size.
PDF pages are rendered at a fixed internal 200 DPI (dots per inch) before encoding. This keeps page geometry consistent and avoids manual resolution setup. After rendering, export settings balance sharpness, file size, and compatibility for the selected output format.
JPG typically flattens transparency into a solid background. JPG output is broadly supported across browsers, messaging apps, and office tools, which makes converted pages easier to preview and share.
PDF pages are rendered into pixels for JPG export, so extreme zoom will eventually show softening. Higher quality settings keep fine text and line art clearer, especially for print or close review.
For crisp text and diagrams, start around 80% to 90% and test one representative page. For quick previews, midrange values often balance readability with smaller download size.
Each page is exported as its own image. Single-page files return one image, while multi-page documents are commonly bundled as a ZIP archive so page order remains easy to manage.
