What is PNG and when should you use it?
PNG is a lossless image format that preserves every pixel exactly and supports full transparency, which makes it ideal for logos, icons, screenshots, line art and any graphic with sharp edges or text. Because it is lossless, a PNG never degrades no matter how many times it is saved. This tool converts one image or a whole batch to PNG entirely in your browser, optionally resizing as it goes, and your files are never uploaded.
How Image to PNG works
How to convert an image to PNG
- Add your images. Drag and drop, or click Add Image(s) — a single file or a big batch.
- Resize if needed. Use the Size control to scale the output; PNG quality is lossless, so there is no quality slider.
- Download. Save each PNG, or click Download All to download the whole batch as a ZIP.
Single or bulk — the same page
Convert one image when you just need a transparent logo, or batch-convert hundreds at once. Each file shows as a card with a checkerboard preview (so you can see transparency) and its file size.
Why convert to PNG?
Choose PNG when you need transparency or pixel-perfect quality — logos, UI assets, diagrams, screenshots and text-heavy graphics all look best as PNG. For photographs, JPG or WebP will usually be much smaller.
Does converting JPG to PNG improve quality?
No — converting to PNG cannot recover detail already lost by a lossy format, but it stops any further quality loss from that point on and gives you a clean, editable, transparent-capable file.
Is it private?
Yes. The conversion happens locally in your browser with the canvas engine; nothing is uploaded and the tool works offline.
