PNG is lossless so the output file may be larger than the JPG source — this is expected and means no quality loss.
PNG is a lossless format — unlike JPEG, PNG images do not degrade in quality with repeated saves. Converting to PNG is ideal for logos, screenshots, and images that need crisp text and edges.
PNG supports an alpha channel (transparency). While JPG source images are opaque by default, the resulting PNG is ready for transparency — useful as a base for further editing in tools like Photoshop or GIMP.
Your image is converted entirely within your browser using the HTML5 Canvas API. No file upload, no cloud processing — your photos remain private on your device.
Convert to PNG when you need: lossless quality (PNG does not compress with quality loss like JPG), transparency support (PNG supports transparent backgrounds), or crisp rendering of text and logos (PNG preserves sharp edges without JPG artefacts). PNG files are typically larger than JPG but retain full image quality.
No. Converting a JPG to PNG does not recover quality that was already lost during JPG compression. The conversion preserves the current JPG quality exactly — it does not add back any lost detail. For best results, always start from the original uncompressed source image.
There is no hard file size limit — the limitation is your browser's available memory. Very large images (above 20 MP) may cause slowness on lower-end devices. For very large photographs, consider resizing first before converting.
