About JPG to PNG · বিস্তারিত

JPG to PNG re-saves your JPG photo as a lossless PNG file on your own device. The width and height stay the same, and from then on every edit and save keeps the picture exactly as it is.

A JPG loses a little detail every time it is saved, because the format compresses by discarding information. PNG stores pixels exactly. Turning a JPG into a PNG cannot bring back detail the JPG already lost, but it stops further loss while you crop, annotate or edit the picture several times.

Expect the PNG to be larger than the JPG, often two to five times larger for a photo. That is normal: lossless storage needs more bytes. If size matters more than editing, keep the JPG.

Run the converter
Press Run JPG to PNG. Your browser draws the photo and encodes it as PNG in a moment.
Save the PNG
The result card shows the new size; Download saves it under the same name ending in .png.

When it helps · কখন কাজে লাগে

A portal that asks for PNG only: Some scholarship, exam or company HR portals list PNG as the accepted signature or logo format. A camera JPG can be re-saved as PNG to pass that check.
Editing in several rounds: If you will add arrows, text or highlights to a screenshot over several sessions, working on a PNG avoids the blocky JPG artefacts that build up with each save.
Preparing a picture for transparency work: Design apps can only cut out a background and keep it see-through in a format like PNG. Converting first gives you a file that can hold transparency later.

Example: a 1.2 MB phone photo

A 12-megapixel phone photo saved as a 1.2 MB JPG commonly becomes a PNG of roughly 5 to 15 MB, depending on how much texture the scene has. The image looks the same; the extra bytes are the price of lossless storage.

বাংলায়: JPG থেকে PNG

এই টুল আপনার JPG ছবিকে ব্রাউজারেই PNG ফাইল বানিয়ে দেয়, ছবি কোথাও যায় না। PNG লসলেস ফরম্যাট, তাই এরপর যতবার এডিট করে সেভ করবেন, ছবির মান আর কমবে না। তবে মনে রাখবেন, JPG-তে আগে যে মান হারিয়েছে তা ফিরে আসে না, আর PNG ফাইল সাধারণত JPG-র চেয়ে কয়েক গুণ বড় হয়। যেসব অনলাইন পোর্টালে শুধু PNG চায়, সেখানে এটা কাজে লাগে।

PNG করলে কি ছবি আরও পরিষ্কার হবে?

না। ছবি যেমন আছে তেমনই থাকবে, শুধু পরের এডিটে আর মান কমবে না।

সাদা ব্যাকগ্রাউন্ড কি স্বচ্ছ হয়ে যাবে?

না, ব্যাকগ্রাউন্ড যেমন ছিল তেমনই থাকে। স্বচ্ছ করতে আলাদা ব্যাকগ্রাউন্ড রিমুভার লাগবে।

Questions people ask · প্রশ্ন ও উত্তর

Does converting JPG to PNG improve quality?

No. It freezes the quality at its current level. Blur or blockiness already in the JPG stays, but no new loss is added when the PNG is edited and saved later.

Why is my PNG so much bigger than the JPG?

PNG keeps every pixel exactly, while JPG throws away fine detail to save space. For photos, a PNG two to five times the JPG size, or more, is normal.

Will the white background become transparent?

No. The converter copies the pixels as they are, so a white background stays white. You need a background remover or an image editor to make it see-through.

Does my photo leave my phone?

No. The JPG is decoded and re-encoded by your own browser, and the download is created on your device. There is no upload step.

Is the camera information kept?

No. The browser redraws the picture, so EXIF data such as the camera model, date and GPS location is not written into the PNG. That can be useful before sharing a photo publicly.

Can I convert many JPGs at once?

This page takes one image per run. Pick the next file after downloading. For batch work in one go, the Image Resizer accepts several files and can output PNG at 100% scale.
