Scan to JPG Converter Online: How to Turn TIFF Scans into JPGs
Scanners save files as TIFF. Here's how to convert scanned TIFF images to JPG online — free, no account needed, ready to share in seconds.
If you've just scanned something — a document, a photo, a form — there's a good chance your scanner saved it as a TIFF file. TIFF is the default format for most flatbed and document scanners because it stores everything without compression. The problem is that almost nothing else wants a TIFF. Email clients struggle with them, phones won't open them, and websites reject them outright. What you actually need is a JPG.
Here's the short answer: upload your TIFF to a free online converter, download the JPG, and you're done. No software to install, no account to create. The rest of this post explains exactly how scanning produces TIFF files, why JPG is usually the right output format, and what to watch for when you convert.
Why does my scanner save files as TIFF?
TIFF (Tagged Image File Format) was designed for archiving. It supports very high bit depths, multiple layers, and lossless compression — which means every pixel the scanner captures is kept intact. For professionals archiving original documents or scanning film negatives, that matters.
For most everyday uses — sending a scanned contract to someone, sharing a photo with family, uploading a form to a website — it doesn't. A TIFF file from a flatbed scanner at 300 DPI can easily run to 20–50 MB per page. The visual quality difference between that and a well-compressed JPG is invisible at normal viewing sizes.
Your scanner saves TIFF by default because it was built to preserve everything. You're free to convert to something more practical afterwards.
What's the difference between TIFF and JPG for scans?
File size. A single scanned page in TIFF might be 25 MB. The same scan as a JPG at high quality is typically 1–4 MB. That difference matters the moment you try to email it or upload it anywhere.
Compatibility. JPG opens in every browser, every phone, every photo app, and virtually every website that accepts image uploads. TIFF opens in some of those — but not all, and often not without a workaround.
Quality loss. JPG uses lossy compression, which means some data is discarded during compression. At high quality settings (80–95%), the loss is imperceptible for scans of documents and photographs. If you're archiving irreplaceable originals, keep the TIFF as a master copy and convert a JPG for sharing. If the scan is for a practical use — a signature page, a printed photo, a receipt — JPG is fine as your only copy.
Editing. If you plan to edit the image significantly, TIFF holds up better across multiple rounds of saving. For scans you're converting once and sending, this is irrelevant.
How to convert a scanned TIFF to JPG online
The process is the same whatever your scanner model or operating system.
Locate your TIFF file. Scanners usually save to a default folder — Documents, Pictures, or a scanner-specific folder. The file will have a
.tifor.tiffextension.Open the converter. Go to the TIFF to JPG converter on share-pics.com. No account required on either end.
Upload your file. Select your TIFF and upload it. The conversion runs on share-pics.com's servers, so it works on any device and browser — you don't need to install anything.
Download the JPG. Once conversion is complete, download your file. It will be a standard JPG, ready to email, upload, or print.
The converter handles files up to 100 MB, which covers the large TIFFs that high-resolution scanners produce.
Does converting a scan to JPG reduce quality?
At high quality settings, not in any way you'll notice. The converter outputs JPG at a quality level designed to keep scanned documents and photographs sharp. Text stays legible, detail in photographs holds, and the file is a fraction of the original size.
The main thing to understand is that quality loss in JPG is cumulative — it compounds if you repeatedly open, edit, and re-save the same JPG. If you convert once and then only share or print the result, quality loss is negligible. If you think you might need to edit the file later, keep the original TIFF alongside the JPG you create for sharing.
What about multi-page TIFF files?
Some scanners save a batch of scanned pages as a single multi-page TIFF. This is common with document scanners and some all-in-one printers when you use the automatic document feeder.
If your TIFF contains multiple pages, it will be converted to a corresponding set of individual JPG images — one per page. You can then share all of them together using the same tool. Share-pics.com lets you upload up to 50 files at once and generates a single private link covering all of them, with an expiry you set between 24 hours and 30 days. That's useful if you've scanned a multi-page document and need to send the whole thing to someone without emailing a stack of attachments.
Does the converter remove EXIF data?
Yes. Share-pics.com strips EXIF metadata from JPEG output by default. For scanned documents this rarely matters — scans don't typically embed GPS coordinates or camera details the way phone photos do. But if you're converting a scanned photograph and want to preserve any embedded metadata, that's worth knowing in advance.
Can I convert other scan formats too?
Scanners occasionally output formats other than TIFF — some save PNG, some save PDF, and some Windows systems produce BMP files. Share-pics.com converts between JPEG, PNG, WEBP, HEIC, GIF, TIFF, and AVIF. If your scanner produced a PNG or HEIC file, the same process applies: upload, convert to JPG, download.
PDF conversion is outside its scope — if your scanner produced a PDF, you'll need a separate PDF-to-image tool before converting.
Do I need an account to use the converter?
No. There's no account required to convert a file, and no account required to receive or download a shared file. You upload, convert, and download. If you use the sharing feature to send the resulting JPG to someone else, they open the link in a browser and download it directly — no sign-up on their side either.
Quick checklist before you convert
- Check the file size. Files up to 100 MB are supported. If your TIFF is larger — which can happen with very high-resolution multi-page scans — consider whether you need the full resolution, or whether scanning at 200 DPI rather than 600 DPI would have served your purpose.
- Decide on archiving. If the document matters long-term (legal paperwork, irreplaceable photos), keep the TIFF as a backup and convert a copy.
- Multi-page files. If you have a multi-page TIFF, expect one JPG per page as output.
- Sharing. If you need to send the converted files to someone, you can do it immediately through the same site — no separate upload step needed.
Scanning produces TIFF because scanners are built to preserve everything. Converting to JPG gives you a file the rest of the world can actually open. The process takes about thirty seconds online, and you don't need to install anything or create an account to do it.
