How to Convert an Image to PNG
Upload images
Choose one or multiple JPG, WebP, HEIC, AVIF, BMP, GIF, or PNG files.
Pick background mode
Preserve transparency, clean a light background, or make white areas transparent.
Set output
Optionally set maximum dimensions or enable target-KB resizing.
Download PNG
Compare each output, download one file, or save the whole batch as a ZIP.
Why This Image to PNG Converter Is Different
Universal image input
Use JPG, WebP, HEIC, HEIF, AVIF, BMP, GIF, PNG, or JPEG as the source.
Transparency options
Preserve existing transparency or remove simple white backgrounds for logos, signatures, and stamps.
Batch and ZIP download
Convert up to 20 images together and package all successful PNG files into one ZIP.
Dimensions and exact KB
Set optional maximum dimensions or let target-KB mode reduce PNG dimensions when needed.
Private local processing
Image conversion and ZIP creation happen inside your browser without a server upload.
Convert Multiple Image Formats to PNG
PNG is useful when you need crisp graphics, transparency, clean form images, stamps, signatures, or files that should not use JPG-style photo compression. This converter lets you process common image formats in one browser-based batch.
Preserve or Create Transparency
Use Preserve for PNG and WebP images that already have transparent pixels. Use White to transparent when a logo, stamp, or signature has a simple light background that should become transparent.
Resize PNG Output to Target KB
PNG is often larger than JPG because it is lossless. If a portal asks for a strict PNG file-size limit, target-KB mode can reduce dimensions to get closer to the required size. If you need JPG output instead, use the Image to JPG converter.
Related Converter Tools
For single-format workflows, use the JPG to PNG converter or PNG to JPG converter. For iPhone source photos, the HEIC to JPG converter remains the best JPG-specific option.

Frequently Asked Questions
Which image formats can I convert to PNG?
You can convert JPG, JPEG, WebP, HEIC, HEIF, AVIF, BMP, GIF, PNG, and other browser-supported images to PNG. HEIC and HEIF use a browser-based decoder before PNG export.
Can I convert multiple images to PNG at once?
Yes. Add up to 20 images, convert them in one batch, download files individually, or download all successful PNG results as a ZIP file.
Can this tool preserve transparency?
Yes. Choose Preserve to keep existing transparent pixels from PNG or WebP images where the browser can decode them.
Can I make a white background transparent?
Yes. Use White to transparent for simple logos, signatures, stamps, and images with plain light backgrounds. Complex photo backgrounds need a dedicated background remover.
Can I resize PNG files to a target KB size?
Yes. Turn on target-KB resizing and enter a limit. PNG is lossless, so the tool may reduce dimensions when needed to get closer to strict upload limits.
Are my images uploaded to a server?
No. Decoding, background cleanup, resizing, PNG encoding, and ZIP creation run locally in your browser. Your images stay on your device.
What happens when I upload an animated GIF?
PNG is a still-image format in this tool, so it exports a single static frame instead of preserving animation.
