TIFF vs PDF vs JPEG vs PNG: Which File Format Should You Use?
Choosing a file format sounds trivial until a form rejects your upload, an email bounces because the attachment is too big, or a print shop asks for something you do not have. TIFF, PDF, JPEG, and PNG are four of the most common formats for images and scanned documents, and each exists for a different reason. This comparison explains what each format does best, where it struggles, and how to decide which one fits your task.
A quick overview of each format
TIFF is a high-quality raster format favored by scanners, photographers, and publishers. It supports lossless compression, high bit depth, and multiple pages, but files are large and browser support is poor.
PDF is a document container. It can hold text, vector graphics, and images across many pages, and it looks the same on every device. It is the standard for contracts, reports, forms, and anything meant to be read or printed.
JPEG is a compressed photo format. It uses lossy compression to make photographs small, at the cost of some detail that cannot be recovered. It is supported everywhere.
PNG is a lossless web format that supports transparency. It is excellent for screenshots, logos, and graphics with flat colors, but its files can be large when used for photographs.
Comparison table
| Feature | TIFF | JPEG | PNG | |
|---|---|---|---|---|
| Compression | Lossless (or none) | Mixed | Lossy | Lossless |
| File size | Very large | Small to medium | Small | Medium to large |
| Multiple pages | Yes | Yes | No | No |
| Transparency | Yes | Yes | No | Yes |
| Opens in browsers | Rarely | Yes | Yes | Yes |
| Best for | Archiving, print | Documents | Photos | Graphics |
Image quality
When quality is the top priority, TIFF and PNG lead because they do not discard information. Open a TIFF, edit it, save it, and repeat the process as often as you like; nothing degrades. JPEG behaves differently. Every time a JPEG is saved, the encoder removes a little more detail, so repeated editing gradually produces blocky artifacts, especially around text and sharp edges. PDF quality depends on what is inside it: a PDF built from a lossless image preserves it well, while one built from a heavily compressed JPEG will look soft.
File size and sharing
Size is where TIFF loses its advantage. A single A4 page scanned in color at 300 DPI can exceed 20 MB as an uncompressed TIFF, but only a few hundred kilobytes as a JPEG and perhaps 500 KB to 1 MB inside a well-made PDF. When a recipient needs to download your file over a mobile connection, or a portal enforces a 10 MB limit, the smaller formats win clearly. This is the most common reason people convert TIFF to PDF.
Compatibility
JPEG, PNG, and PDF open almost anywhere: phones, laptops, tablets, email clients, and web browsers. TIFF is the outlier. Safari can display it and the major operating systems include basic viewers, but Chrome, Firefox, and Edge do not render TIFF images. Many online forms, chat apps, and content management systems flatly refuse it. If you are not certain what software your recipient uses, PDF is the safest choice for documents and JPEG for photos.
Working with text and documents
PDF stands apart for documents because it is a page-based format. It keeps layout consistent, supports searchable text through OCR, allows bookmarks and links, and can be signed, password protected, and printed with predictable results. A multi-page TIFF can store pages too, but it offers none of those reading features. For contracts, invoices, applications, and scanned books, PDF is clearly the better format for distribution.
Working with graphics and the web
If you are publishing a logo, interface screenshot, or diagram on a website, PNG is usually ideal. It keeps sharp edges and supports transparent backgrounds. For website photographs, JPEG remains a good default, although newer formats such as WebP and AVIF can be even smaller. TIFF and PDF are rarely used for web page images because they are not designed for inline display.
Which format should you choose?
- Archiving an original scan or photo: TIFF, because it preserves every detail for future use.
- Emailing or uploading a document: PDF, because it is compact, universal, and keeps pages together.
- Sharing a photograph online: JPEG, because it balances quality and size.
- Posting a screenshot or logo: PNG, because it stays crisp and supports transparency.
- Sending files to a professional printer: ask what they prefer; TIFF and print-ready PDF are both common.
Using more than one format together
You do not have to choose only one. The most effective workflow separates preservation from distribution. Keep a TIFF master of anything valuable, then create a PDF or JPEG copy for everyday sharing. If you ever need a different output, you can regenerate it from the master without any loss. Converting a TIFF to a PDF is a one-way, practical step: it creates a convenient copy while your original stays untouched.
When you need that conversion, a private browser-based tool makes it painless. Try the free TIFF to PDF converter, which processes everything on your own device, supports multi-page files, and lets you choose page size and quality.
Summary
TIFF is best for quality and storage, PDF for documents, JPEG for photographs, and PNG for graphics. Matching the format to the job avoids rejected uploads, bloated emails, and avoidable quality loss. When in doubt, remember a simple rule: archive in TIFF, share in PDF.
