Render selected PDF pages into genuine multipage TIFF with chosen page order, intrinsic orientation and color or grayscale pixels.
LOCAL FILE CONVERSION
Add PDFs, choose pages in the order you need, then download verified multi-page TIFFs, separate TIFF pages, or a ZIP.
Up to 10 PDFs · 25 MiB / 200 source pages per PDF · Browser only; no uploadPDF.js renders intrinsic rotation, page size and aspect ratio on white paper. Each selected page becomes a real TIFF IFD, and all IFDs, DPI metadata, dimensions and decoded pixels are checked before files are published. RGB and grayscale use 8-bit samples; black & white uses packed 1-bit pixels. Grayscale and thresholding intentionally change colors. Deflate falls back to validated uncompressed output only when needed, with a warning.
Limits remain 25 MiB / 200 source pages per PDF; at most 10 selected pages, 8192 pixels per edge and 16 million total rendered pixels per conversion. Retained TIFFs and ZIP are limited to 64 MiB. Pages run sequentially; canvas/PDF resources and owned URLs are released on completion, reset or unmount. TIFF is raster output without searchable PDF text. No uploads, external APIs, OCR or hidden downscaling.

Render selected PDF pages into genuine multipage TIFF with chosen page order, intrinsic orientation and color or grayscale pixels. Uses PDF.js rendering and installed UTIF encoding, not renamed PNG/JPEG files. Select 72, 150 or 200 DPI; 150 DPI is the default. Classic multipage TIFF uses uncompressed 8-bit RGBA channels with DPI metadata and white page backgrounds. Grayscale changes channel values, not the four-channel storage layout. Output pixels are decoded and compared before download. This is raster output without vector/text layers or PDF interactivity. Input ≤25 MiB / 200 source pages; output ≤10 selected pages, 8192 pixels per edge and 16 million total pixels (about 64 MiB). Preview shows the first rendered page.
Source files, filenames and document content stay in browser memory. No conversion uploads, external processing services, file persistence or content analytics are used. Cancel/reset/unmount discards pending work and owned URLs; ordinary page requests may still be logged.
Yes. Installed UTIF encoding writes classic TIFF directories and actual rendered page samples. Page count, dimensions and decoded pixels are checked; PNG/JPEG bytes are not renamed as TIFF.
Enter selected pages/ranges in the intended order, such as 2,1-3. PDF.js applies the source page’s intrinsic rotation during rendering. TIFF pages follow the entered order with orientation already represented in their pixels.
Choose 72, 150 or 200 DPI, with 150 DPI as the default. Higher resolution increases pixel count and file size. DPI metadata is written alongside the actual raster dimensions.
Yes. Grayscale converts rendered RGB values to gray while retaining the same 8-bit RGBA storage layout. It is not a bilevel fax TIFF and does not necessarily reduce file size. Page backgrounds are white.
Encoding is lossless relative to the rendered pixel buffer, which is decoded and compared before download. Rasterization does not preserve PDF vector detail, searchable text, forms or other interactivity. The preview shows the first rendered page.
All rendering and encoding stay in browser memory. Input is limited to 25 MiB / 200 source pages; TIFF to 10 selected pages, 8192 pixels per edge and 16 million total pixels. Uncompressed output can approach 64 MiB. Reduce DPI or pages if limits are exceeded; reset/cancel releases work.
