JPEG is treated as a JPG synonym. GIF, BMP, SVG, HEIC and TIFF remain outside this ordinary raster converter.

Format comparison
Choose for the image you have.
JPG
Best for
Photos
Smaller lossy files and broad compatibility.
PNG
Best for
Transparent graphics
Lossless pixels and alpha transparency.
WebP
Best for
Modern web delivery
Efficient lossy output with transparency support.
Transparency needs a deliberate background.
PNG and WebP may contain transparent pixels. JPG cannot, so the studio warns you and lets you preview white, black or a custom color before encoding.
Conversion stays in this browser.
The ordinary raster pipeline uses browser decoding and canvas re-encoding. Files are not uploaded to the Nexynto server for this workflow.
Frequently asked questions
Image conversion, explained clearly
How do I convert an image to PNG?
Add a JPG or WebP image, choose PNG as the output format, review the live preview, then convert. PNG keeps transparency and uses lossless browser encoding.
How do I convert PNG to JPG?
Choose JPG and select a background. Transparent PNG pixels must be flattened because JPG does not support transparency.
Can I convert JPG to WebP?
Yes. Select WebP and choose a quality preset or custom encoder quality. Dimensions remain unchanged.
Does converting images reduce quality?
PNG is lossless, while JPG and WebP use adjustable lossy encoding. The live preview and measured output size help you choose deliberately.
What happens to transparency when converting PNG to JPG?
The selected white, black or custom background replaces transparent pixels. The studio warns you before conversion.
Does Nexynto preserve image metadata?
No. Browser canvas re-encoding removes most EXIF, GPS, camera and other metadata. The current studio states this explicitly.
Can I convert many images at once?
Yes. Add multiple images, search or sort the bounded workspace, and apply one output profile to the full batch.
What is the difference between JPG, PNG and WebP?
JPG suits photos and broad compatibility, PNG suits transparent or lossless graphics, and WebP provides efficient modern web delivery.
Are my images uploaded to a server?
No. Ordinary JPG, PNG and WebP decoding, preview and re-encoding happen in your browser.
Can I convert images on mobile?
Yes. The mobile studio places the selected file and preview before the settings and provides a sticky conversion action.
