Fast Format Transformation Without Server Delays
Different platforms demand different graphic file formats. E-commerce platforms and web design standards favor modern WebP for lightweight performance, while legacy printing setups and identity portals often demand strict JPG or lossless PNG files.
Toolnova Image Converter converts entire batches of images locally in your browser using native HTML5 Canvas capabilities. You can seamlessly switch transparent PNGs to WebP or turn bulky photos into lightweight JPEGs.
Because no file data is ever transmitted across the network, conversions occur at maximum CPU speed without server queues or file upload wait times.

Frequently asked questions about Image Converter
Common questions about usage, privacy, limits, and browser compatibility.
Is WebP better than JPG?
WebP generally produces a smaller file than JPG at the same visual quality, which means faster page loads, and it also supports transparency. JPG is still the safer choice for older software, print shops, and upload portals that only accept .jpg files.
How do I convert PNG to JPG without losing quality?
Choose JPG as the output format and keep the image at its original dimensions, so the converter re-encodes it at full resolution instead of shrinking it. Because JPG is a lossy format, some fine detail is always discarded, which is normal and typically invisible at normal viewing sizes. Any transparent areas get filled with a solid background color you select during conversion.
Is this image converter safe?
Files are converted locally in your browser with HTML5 Canvas, so nothing is uploaded, stored, or passed to a third party. There is no account required, no watermark on the results, and no copy of your image kept anywhere.
What happens to transparent areas when I convert PNG to JPG?
JPG cannot store transparency, so transparent pixels are replaced with a solid fill. The converter includes a background color option, and white is used if you leave it unchanged. Choosing PNG or WebP as the output instead keeps those transparent areas intact.
Can I convert several images at once?
Batch conversion is supported: add a group of JPG, PNG, WebP, or GIF files, pick one target format, and let the tool process them together. You can then save the files one by one or export the entire batch as a ZIP archive.
Does converting an image change its dimensions?
Format conversion keeps the original width and height, so a 1200 by 800 photo stays 1200 by 800 afterward. Only the encoding changes, which means a WebP copy looks the same on screen but often weighs far less.
