Bulk PNG to TIFF Converter
Drop a bunch of PNGs here and get a ZIP full of TIFFs back. No upload, no nonsense. I got tired of converting one at a time, so I built this. Keeps your images private too.(Need reverse conversion? Try our TIFF to PNG → tool instantly)

⚙️ Convert & Download
Your files are safe. All conversion happens inside your browser. I can't see your images, and they never touch a server. Even works offline.
Why I Built a Bulk PNG to TIFF Converter
A client once asked me to send a batch of 30 screenshots as TIFF files. I tried converting them one by one with some online tool, and it took forever. I also wasn't sure where my files were going — the privacy policy was buried somewhere. That night I cobbled together a script to do it locally, and eventually it became this page.
This bulk PNG to TIFF converter does exactly what it says. You throw in a bunch of PNG files, click a button, and get a ZIP with all the TIFF versions. No watermarks, no file size downgrades. It's all done with JavaScript in your browser, so your images never leave your computer. I've used it on my phone, too — works fine as long as you're not trying to convert a hundred 50‑megapixel photos at once.
If you just need to batch convert PNG to TIFF for printing or archiving, this should do the job. The TIFFs use LZW compression, which is lossless, so you don't lose any quality. I mostly rely on it when I'm prepping graphics for a print shop that insists on TIFF format, and I have a folder full of PNG exports. Saves me a ton of clicking around.
What Makes This Batch Converter Useful
📁 Handles Dozens at Once
I've tested it with 50 PNGs and it didn't crash. It processes each one separately and then bundles them into a ZIP. No weird batch limits or "pro" upgrades needed.
🔏 Offline & Private
You can literally turn off your internet after the page loads. It'll still work. I built this because I don't trust random servers with my files, especially when they're work‑related.
🎯 Lossless Quality
The conversion uses LZW compression inside TIFF, which is lossless. Your pixels stay exactly the same, just wrapped in a different file format. Great for print.
💸 Actually Free
No ads, no email walls, no daily limits. I just leave it here for people who need a free PNG to TIFF batch tool without jumping through hoops.
Questions I Get About This Tool
Can I download each TIFF separately?
Right now it only does a ZIP with everything inside. I usually just unzip the folder after downloading. If you only want one file from the batch, you can delete the rest from your computer — or just use a single‑file converter.
Does the conversion keep transparency?
Yep, if your PNG has an alpha channel, the TIFF will keep it. I've used this for logos with transparent backgrounds and they came out fine.
What's the biggest batch I can convert?
I set a 30 MB per‑file limit, and the total batch size depends on your browser's memory. I've done 40 files at once without issues. If your PNGs are huge (like 50 megapixels each), you might want to split them.
Will the file names stay the same?
Each TIFF gets the same name as the original PNG, just with a .tiff extension. Inside the ZIP they're all nicely organized — no random numbers or anything.
Is my data really safe?
Absolutely. I can't emphasize this enough: the whole converter runs in your browser. I don't see your files, they don't go to a server, nothing. You can inspect the code yourself if you're paranoid (I do the same thing).
Why TIFF instead of staying with PNG?
TIFF is an industry standard for print and archiving. Many print shops, publishers, and graphic designers require TIFF because it supports layers, multiple pages, and high bit depths. This tool is handy when you're stuck between a PNG export and a TIFF requirement.
