About PNG to TIFF · বিস্তারিত

PNG to TIFF writes a PNG's pixels, including its alpha (transparency) channel, into an uncompressed TIFF file in your browser. No quality is lost, since both formats are lossless; the TIFF is just larger.

PNG is the web's lossless format; TIFF is the lossless format of print and publishing. Logos, illustrations and screenshots often start as PNG and must be handed to a printer, typesetter or archive that asks for TIFF.

The conversion copies pixels one to one into an uncompressed RGBA TIFF using the UTIF library. Because transparency travels in the fourth channel, programs that understand TIFF alpha show the cut-out cleanly; some older viewers may display it on black or white.

How to use it · কীভাবে ব্যবহার করবেন

  1. Add the PNG

    Select a .png file, for example a logo or illustration.

  2. Convert to TIFF

    Press Run PNG to TIFF; the RGBA pixels are written into a TIFF.

  3. Download

    Save the .tiff file and send it to the printer or archive.

When it helps · কখন কাজে লাগে

Logos for printing presses
Hand a PNG logo with transparent background to a print shop or newspaper that only takes TIFF artwork.
Book and journal figures
Publishers often require TIFF for figures and charts; a PNG chart from a spreadsheet or plotting tool can be converted without loss.
Archiving design assets
Some organisations store master graphics as TIFF; converting PNG keeps every pixel unchanged.

What you get

  • Lossless: pixels identical to the PNG
  • Alpha channel stored as a fourth channel
  • Uncompressed RGBA TIFF
  • Width and height unchanged
  • Runs in the browser with the UTIF library

বাংলায়: PNG থেকে TIFF

লোগো বা চার্ট সাধারণত PNG থাকে, কিন্তু ছাপাখানা, পত্রিকা বা প্রকাশনা সংস্থা অনেক সময় TIFF চায়। এই টুল ব্রাউজারেই PNG-কে TIFF বানায়, স্বচ্ছতার চ্যানেলসহ, আর কোনো মান হারায় না। তবে TIFF ফাইল কমপ্রেশন ছাড়া হয় বলে অনেক বড় হয়। CMYK বা DPI লাগলে পরে এডিটরে ঠিক করতে হবে।

স্বচ্ছ ব্যাকগ্রাউন্ড থাকবে?

হ্যাঁ, স্বচ্ছতার তথ্য ফাইলে থাকে; বেশিরভাগ এডিটরে তা দেখা যায়।

মান কি কমবে?

না, দুটো ফরম্যাটই লসলেস, পিক্সেল হুবহু থাকে।

Questions people ask · প্রশ্ন ও উত্তর

Is the transparency kept in the TIFF?

The alpha channel is written into the file. Editors such as Photoshop, GIMP and Affinity normally show it as transparency; a few simple viewers ignore it and show a solid background.

Does converting PNG to TIFF lose quality?

No. Both are lossless and the pixels are copied exactly.

Why is the TIFF bigger than my PNG?

PNG compresses its pixels; this TIFF does not. A 2000 × 2000 logo takes about 16 MB as uncompressed RGBA TIFF.

My printer asked for a CMYK TIFF at 300 DPI. Is this enough?

Not on its own. This tool writes RGB with alpha and no DPI value. Open the TIFF in an editor to convert it to CMYK and set the resolution, or ask the printer whether RGB is acceptable.

Is anything uploaded?

No. Your browser reads the PNG and assembles the TIFF on your device.
