How to Convert PDF to TIFF Online for Free

Direct answer: You can convert PDF to TIFF online for free with the PDF to TIFF tool: every page is rendered as a TIFF image, lossless and resolution-tagged, at the DPI you choose, and the result is delivered as a ZIP of page files, one TIFF per page. TIFF is the print and archive standard, so this conversion suits press work, long-term archiving, and any workflow where a page must become a high-quality image without lossy compression.

The one-file-per-page delivery is a deliberate choice for compatibility. A multi-page TIFF exists as a format, but not every viewer, printer, or archive system handles it in the same way, and a single faulty page can complicate the whole file. Separate page files, named by page number, open everywhere TIFF is supported, can be processed one at a time, and can be replaced individually if one page needs to be re-rendered. For print and archive work, that predictability matters more than the neatness of a single file.

Why TIFF, and why lossless matters for print

TIFF is a lossless image format, which means that saving a page as TIFF does not discard image detail to save space, the way a lossy format does. Each time a lossy image is saved, detail is lost, and repeated saves compound that loss. A TIFF, by contrast, preserves the rendered page as it was produced, so that a file opened, copied, or archived today will still carry the same detail when it is opened again months or years later. That stability is why TIFF remains a standard for print shops, archives, libraries, and publishers, even though its files are larger than lossy alternatives.

TIFF files are also resolution-tagged, meaning that the file itself records the resolution at which the page was rendered. A print system reading that tag knows the intended size and sharpness of the image, rather than having to guess from pixel dimensions alone. That tag, combined with lossless storage, makes TIFF a reliable handover format: the person receiving the file does not need to know your conversion settings, because the file carries its own resolution information, and the image data has not been degraded by compression in transit.

Choosing DPI: 150, 200, or 300

DPI, or dots per inch, controls how many pixels are rendered for each inch of the page, and therefore how sharp the image will be when printed and how large the file will become. At 150 DPI, a page is rendered with enough detail for proofs, internal review, and draft printing, while keeping file sizes manageable. At 200 DPI, detail improves noticeably for general print work, and the file grows accordingly. At 300 DPI, the rendering is suitable for press and archive use, where fine text, thin lines, and small details must survive printing at full quality, and the files are correspondingly larger.

Choose DPI from the destination, not from a habit of always picking the highest number. A proof that will only be viewed on screen or printed for a quick check does not need press resolution, and rendering it at 300 DPI will only slow the conversion and enlarge the download for no visible benefit. A file destined for a print shop or a permanent archive, on the other hand, should be rendered at 300 DPI from the start, because a low-resolution render cannot be sharpened back into a high-resolution one afterwards. If you are unsure, render a single test page at your chosen DPI and inspect it at full size before converting the whole document.

Step by step: converting your PDF to TIFF

Load the PDF, choose the DPI that fits the destination, and start the conversion. Each page is rendered in turn, and the finished files are collected into a ZIP, with one TIFF per page, named by page number. Download the ZIP, extract it, and check the first and last pages at full size, plus any page with fine text, small diagrams, or detailed images, because those pages are where a wrong DPI choice shows up first. A quick visual check of a few representative pages is more useful than a quick glance at every page at thumbnail size.

If the document is long, plan the conversion in stages rather than attempting the whole file at once, especially at 300 DPI, which is heavy in a browser tab when applied to many pages. Splitting a large document into batches, converting each batch, and then combining the resulting TIFF files in order will complete reliably where a single huge conversion might strain the tab. Keep the batches in order, name them clearly, and verify the page count after combining, so that no page is duplicated or lost between batches.

• Open the free tool and load the PDF you want to convert.
• Choose 150 DPI for proofs, 200 DPI for general print, or 300 DPI for press and archive.
• Start the conversion and let every page render in turn.
• Download the ZIP of page files, one TIFF per page, named by page number.
• Extract the ZIP and check first, last, and detail-heavy pages at full size.
• For long documents at 300 DPI, split into batches and convert in order.
• File the TIFFs with a clear name noting the DPI used.

TIFF versus JPG versus PNG: picking the right image format

TIFF, JPG, and PNG each suit a different job, and choosing between them is a matter of destination, not of one format being universally best. JPG is a lossy format designed for sharing and for photographs on the web, where small file size matters more than perfect preservation of detail. It is ideal for sending a quick preview, posting an image online, or emailing a photograph, but it is a poor choice for a press file or an archive master, because each save discards detail that cannot be recovered.

PNG is a lossless format designed for screens, with excellent support for sharp graphics, text, and transparency, and it is the natural choice for a page image that will be viewed on a screen, embedded in a presentation, or used on a website. TIFF is the lossless, resolution-tagged format designed for print and archiving, where file size is secondary to fidelity and to the resolution information a print system needs. When the destination is a printer or an archive, choose TIFF. When the destination is a screen, choose PNG. When the destination is casual sharing, choose JPG. That simple rule will prevent most format mistakes.

Converting between these formats later is possible, but it cannot restore detail that was lost in an earlier lossy step. A TIFF rendered at 300 DPI can be turned into a JPG for sharing without harming the TIFF master, because the master remains untouched. A JPG, on the other hand, cannot be turned back into a true TIFF master, because the detail discarded when the JPG was made is gone. Always keep the TIFF as the master for print and archive work, and derive sharing copies from it, rather than the other way round.

Handling large documents and checking the output

Large documents deserve a plan before conversion, not after a tab struggles. At 300 DPI, many pages are heavy in a browser tab, because each page becomes a large, detailed image held in memory during the conversion. Splitting the document first, converting in batches, and keeping the batches in order is the reliable route, and it also gives you natural checkpoints: if a batch fails or a page looks wrong, only that batch needs to be redone, not the whole document. Note the DPI and the batch order in the folder name or in a short readme, so that a future reader knows exactly how the TIFFs were produced.

Checking the output means more than confirming that files exist. Open a few TIFFs at full size and look at small text, thin rules, and fine image detail, because those are the elements that suffer first from a too-low DPI or a rendering problem. Confirm that page numbering in the filenames matches the original document order, and that no page is blank, duplicated, or missing. A TIFF set that passes those checks is ready to hand to a print shop or to file in an archive with confidence.

If a long PDF needs to become smaller files before conversion, or if pages need to be reorganised first, do that preparation before rendering, because re-rendering at 300 DPI is the expensive step. You can learn the page-splitting step in our guide to dividing a PDF into smaller files, and find more conversion guides on other Asad Webs conversion guides.

Filing TIFFs for print shops and archives

When handing TIFFs to a print shop, include the information the shop needs alongside the files: the document title, the page count, the DPI used, and any colour or size requirements the shop has specified. A ZIP of page-numbered TIFFs plus a short note with those details will be processed far faster than a set of files with no context, because the shop will not need to guess at resolution, order, or intended size. If the shop specifies a different DPI or a particular TIFF variant, render to that specification from the original PDF, rather than converting an existing TIFF set, so that the new files are rendered cleanly at the requested settings.

For archiving, the same clarity pays off over years rather than days. Store the TIFFs in a folder named for the document, with the DPI and the conversion date in the folder or file naming, and keep the original PDF alongside them, so that future readers can re-render if standards change. TIFF's lossless, resolution-tagged nature makes it a good archive format, but good filing is what makes an archive usable: a perfectly rendered TIFF that cannot be found, or whose resolution is unknown, is little better than a lost document. A short, consistent naming habit, applied every time, is the cheapest archive insurance there is.
