Lossless TIFF compression: smaller files, identical pixels

Compress TIFF files without giving up the format
A TIFF straight off a scanner or a camera can run to 50 or 100 MB for a single page. That is not a fault in the file. TIFF was built for print and archiving, so it stores every pixel exactly as captured and throws nothing away. The size is the whole point of the format. It only becomes a problem when you need to email the file, attach it to a form, or upload it somewhere with a size limit.
Your pixels come back exactly as they went in
This is lossless compression. Not “almost lossless”, not “no visible difference at normal viewing size”. The image data that comes out is identical to the image data that went in, and the file is smaller because it is packed more efficiently rather than because detail was removed. Open the result next to the original at 400 percent and there is nothing to find.
That distinction matters more here than it would for a holiday photo. Most free tools advertising TIFF compression quietly re-encode your image as a JPEG and leave it inside the TIFF wrapper, which looks fine on a screenshot and falls apart on a scanned page: fuzzy halos appear around the letters, thin lines break up, and an archive copy stops being a faithful copy. If you are compressing a scan for a records system, a court filing or a print shop, that is the difference between a file you can hand over and one you cannot.
Why your TIFF is so large
Most image formats decide compression for you. A JPEG is always compressed. A PNG is always compressed. You cannot switch either one off. TIFF works differently: it is a container, and whatever program wrote the file chose what happens inside it. Photoshop may have saved yours with ZIP compression. A scanner may have used LZW. A microscope, a medical scanner or an older fax device may have used none at all, and that is where the 100 MB files come from. Two TIFFs of the same photograph can differ in size by a factor of five because of that one setting, with no visible difference between them.
Compressing is not the same as converting
Converting a TIFF to JPEG makes it smaller, but you get a JPEG back. That is fine for a photo you are posting online and wrong for a scan you need to keep, print or submit. This tool leaves the file a TIFF. Your archive stays an archive, your print shop still gets what it asked for, and the file still opens in the same software it opened in before.
TIFF or TIF, same file
You will see both spellings, and people search for both. They are the same format. The three letter version is left over from MS-DOS, which could not handle a fourth character in a file extension, and Windows kept it around long after the limitation was gone. Rename a .tif to .tiff and nothing breaks. Both work here.
Scanned documents and the pages inside them
Scanners are the single most common reason people end up looking for this page. A department scans a stack of paper at 600 DPI, the files land at 40 MB each, and the document system rejects them. Scanned text is also the easiest kind of image to compress, because a page of black type on white paper contains far less real information than a photograph does. If your TIFF is a scanned page rather than a picture, expect a bigger reduction than you would get from a photo.
One TIFF can also hold many pages at once, which is how most document scanners save a stack of paper. Those stay together here. Every page is read and written back into one compressed TIFF, in the same order, rather than being split into a file per page.
Nothing to set, and nothing to get wrong
There are no quality sliders, no compression menus and no advanced tab. One level is applied to every file, chosen to be the point where scans and photographs both come out noticeably smaller without the result looking wrong. Upload, wait, download. If you need fine control over compression type and depth, that is a job for desktop software, and this tool is not pretending otherwise.
When to compress, and when to convert instead
Compression is the right answer when the file has to stay a TIFF. When it does not, changing the format usually saves more. This is roughly how the choice breaks down.
| What you have | Better option |
|---|---|
| A scan you have to archive, print or submit as-is | Compress it and keep it TIFF |
| Several scanned pages that belong together | Turn them into one PDF |
| A photo headed for a website or an email | Convert to JPEG or WebP |
| Line art, a logo, or anything with transparency | Convert to PNG |
Getting your files back
One file in, one file out, downloaded straight away. Upload a folder of scans instead and you can take them one at a time as each is ready, or grab everything in a single ZIP once the batch is finished. Original filenames survive the trip, so a set of numbered scans stays in order and you are not left renaming a folder afterwards.
There is nothing to install and no account to make. The tool runs in your browser, adds no watermark, and never touches the original on your own machine: what you download is a new copy.
What happens to your files
Files travel over an encrypted connection, get compressed, and are deleted from the server an hour later. Nothing is kept, and nothing is used for anything else.
What you get
- Lossless: the image data out is identical to the image data in, so scans stay archive quality
- A smaller TIFF that is still a TIFF, openable in the same software as before
- Both .tif and .tiff accepted, with the extension you uploaded preserved
- Multi-page scans stay in one file, in the same page order
- Download one file at a time as it finishes, or the whole batch as a ZIP
- No account, no install, no watermark, and files deleted from the server an hour later
What’s next?
If those scans belong together as one document, TIFF to PDF merges them and usually lands smaller than the images did. Already have the PDF and still need it lighter? Compress PDF handles that. And if you converted your images to PNG along the way, Compress PNG is the next stop.
Frequently Asked Questions
Because TIFF does not compress by default. It was designed for print and archiving, where keeping every pixel matters more than saving space, so a program can write a TIFF with no compression at all. Scanners, microscopes and older imaging equipment often do exactly that. The same photo saved with LZW or ZIP compression inside the TIFF can be a fraction of the size, with nothing visibly different about it. That is what this tool changes.
It stays a TIFF, and it loses nothing. The compression here is lossless, which means the image data you download is identical to the image data you uploaded and the file is smaller only because it is packed more efficiently. This is worth checking wherever you compress a TIFF, because a lot of free tools re-encode the picture as a JPEG and leave it wrapped in a TIFF container. That looks acceptable on a photograph and ruins a scanned page, where you get fuzzy halos around the letters. If you wanted a JPEG or a PNG on purpose you would need a converter rather than a compressor.
Nothing. They are the same format with two spellings. MS-DOS allowed only three characters in a file extension, so .tif was the version that survived there, and Windows carried it forward long after the limit disappeared. Rename one to the other and nothing breaks. Both are accepted here, and you get back the same extension you uploaded.
It depends on what is in the picture, so no honest tool can promise you a number before it has seen the file. A scanned page of black text on white paper compresses very well, because most of the page is one flat colour and there is little real information to preserve. A detailed photograph with fine texture and gradual colour changes compresses much less. A TIFF that was already saved with compression also has less room left than one saved raw. There are no settings to choose: one compression level is applied to everything, so there is nothing to get wrong.
Yes. A TIFF can hold many pages in one file, which is how most document scanners save a stack of paper, and every page is read and written back into a single compressed TIFF. You do not get one file per page and you do not lose the page order. If you would rather have those pages as one document instead of one image, converting the TIFF to PDF is usually the better move, and it normally ends up smaller than the images did.
A single file downloads on its own as soon as it is ready. For a batch you can take each file individually as it finishes, or download the whole set as one ZIP, whichever suits how you are going to use them. Original filenames are preserved either way, so numbered scans stay in order. As for the files themselves: they are sent over an encrypted connection, compressed, and deleted from the server an hour later. Nothing is stored beyond that and nothing is used for any other purpose. The original on your own machine is never touched, so if you are unhappy with the result you still have what you started with.
