How It Works

TIFF is a 1980s desktop-publishing format that survived because it can hold image data with no lossy compression at all, which is exactly why scanners, microscope cameras, GIS software, and prepress workflows still emit 50-200 MB files. That fidelity becomes dead weight the second you try to email a scan or drop a photo onto a web page. This tool decodes the TIFF, reads its raw pixels, and re-encodes them as a baseline JPEG at a quality setting tuned to cut size hard while keeping photos clean. Everything happens on your own machine. The file is read into memory, decoded, painted to a canvas, and handed back as a download. Nothing is uploaded, so scanned contracts, ID documents, and client photos never leave your device. JPEG is lossy by design, so the output trades some pixel-level accuracy for a far smaller file. For photographs and continuous-tone scans the difference is hard to see at normal viewing sizes. For line art, text-heavy documents, or anything you intend to archive or reprint, keep the original TIFF as your master and treat the JPEG as a working copy. One thing to know up front: TIFF can pack many pages into a single file, but JPEG holds exactly one image, so this converter outputs the first page. If you need every page, split the TIFF first.

max Resolution Limited only by your device's memory
processing Time Instant, runs in your browser

Key Benefits

  • Turns 50-200 MB scanner output into a file small enough to email or post
  • Runs entirely in your browser, so confidential scans never leave your device
  • JPEG opens everywhere TIFF won't, including chat apps, browsers, and phones
  • No file-size cap or conversion quota, and no account required
  • Strips the uncompressed bulk that inboxes and web pages choke on
  • Reads grayscale, RGB, and CMYK TIFFs with no plugins or setup

Common Use Cases

  • Sharing scanned documents and receipts that scanner software saved as oversized TIFFs
  • Putting archival or museum photo scans online at a sane file size
  • Emailing prepress proofs to clients who only need to see them, not print them
  • Shrinking storage for large photo libraries kept in TIFF
  • Posting microscope, satellite, or technical imagery where exact fidelity isn't required
  • Pushing images through chat or upload forms that reject or won't preview TIFF

Pro Tips

  • Keep the original TIFF as your master; the JPEG is a one-way, lossy copy
  • For text-heavy or line-art scans, choose PNG instead; JPEG smears the sharp edges
  • For print or color-critical work, convert CMYK TIFFs in prepress tools with ICC profiles, not to JPEG
  • If a TIFF errors out, re-export it as standard uncompressed or LZW TIFF and retry
  • Split multi-page TIFFs first if you need every page, since this outputs only the first one

Frequently Asked Questions

Usually a lot smaller, because most TIFFs store pixels uncompressed or with lossless LZW. A smooth photograph or scan can drop to a small fraction of the original size, while a busy, high-detail page saves less. The reduction comes from two things at once: JPEG's lossy compression and the fact that you are discarding TIFF's uncompressed overhead.
Yes. JPEG uses lossy DCT compression, so some detail is discarded permanently. At normal viewing sizes the loss is usually invisible for photos and continuous-tone scans. The visible artifacts cluster around sharp edges, text, and fine line art, so those are the cases where the trade-off actually matters.
It reads the file but only converts the first page, because JPEG cannot store multiple images in one file. Multi-page TIFFs are common from document scanners and fax software. If you need every page, split the TIFF into single pages first (most PDF or imaging tools can do this) and convert each one separately.
No. Keep the TIFF as your master copy. The conversion is one-way: once detail is compressed out, converting the JPEG back to TIFF will not bring it back. Use the TIFF for archiving, reprinting, and future editing, and use the JPEG purely as a lightweight copy for sharing and the web.
Plenty of TIFFs from print workflows use CMYK color or 16 bits per channel. JPEG here is 8-bit and effectively sRGB, so the converter maps the image down to that during encoding. Colors come across as closely as the format allows, but for exact print color you should convert through dedicated prepress software with proper ICC profile handling, not to JPEG.
No. The whole conversion runs in your browser using your device's own CPU. The TIFF is never sent to a server, and nothing is stored once you close the tab. That makes it the safe choice for sensitive material like scanned contracts, medical images, or personal documents.
TIFF is a flexible container with many compression schemes and tags, and a few exotic variants (certain JPEG-in-TIFF, old or vendor-specific codecs, or a truncated file) are not decodable in the browser. If a file errors out, re-export it from your editor as a standard uncompressed or LZW TIFF and try again; that resolves most cases.
For sharing, yes, by a wide margin. Browsers, phones, chat apps, and email clients all display JPEG natively, while TIFF often refuses to preview and downloads as a raw file the recipient cannot open. If the goal is for someone to simply see the image, JPEG is the practical format.
