All processing happens locally in your browser using WebAssembly. Your files are never uploaded to any server and never used to train AI models.
Convert white backgrounds to transparency — ideal for logos and overlay graphics.
PNG uses lossless compression — no quality degradation unlike repeated JPEG saves.
No upload required — your image is converted locally on your device.
LovePDFs is a completely free alternative to Adobe Acrobat, Smallpdf, and ilovepdf. Unlike other online tools that upload your files to remote servers, LovePDFs processes everything in your browser using WebAssembly technology. Your files never leave your device — not even for a second.
This makes LovePDFs the right choice for sensitive documents — contracts, medical records, financial files, government forms, and anything you wouldn't want sent to a third-party server. It's also the only major PDF tool suite that is GDPR-friendly by design, since no personal data or file content ever leaves your browser.
Upload your JPG, enable the transparent background option to replace white areas with transparency, and click Convert to PNG.
PNG is better for logos, graphics, and images that need transparent backgrounds. JPG uses lossy compression that degrades quality with each save.
Upload your JPG, enable the "Replace white with transparency" option, and convert to PNG. White areas become fully transparent.
JPG files use lossy compression, which introduces pixel artifacts when saved repeatedly. Converting JPG to PNG converts the image to a lossless format, preserving quality for future edits.
PNG format is ideal for graphic design, print layout preparation, and editing. It maintains sharp lines, text boundaries, and solid color blocks without creating artifacts.
Graphic designers convert JPG logos to PNG before editing. Web developers convert assets to prepare icons. Artists convert compressed drafts to save lossless final versions.
The script reads your JPEG image coordinates and writes them into a standard PNG pixel grid locally in your browser tab. No compression artifacts are added during this local operation.
