TL;DR: Re-saves a JPEG as lossless PNG; it can't recover detail already lost to JPEG compression, but prevents further loss and supports transparency on later edits.
Convert JPG to PNG online for free — change JPEG photos to lossless PNG, preserving every detail and supporting transparency on re-edits. Drag-and-drop multiple files, processed and discarded server-side.
Using JPG to PNG doesn't require an account, an email address, or a paid plan. Your file is held in isolated temporary storage only for the duration of processing, then permanently unlinked. No watermarks, no upsells, no behavioural tracking.
Convert JPG to PNG online for free — change JPEG photos to lossless PNG, preserving every detail and supporting transparency on re-edits. Drag-and-drop multiple files, processed and discarded server-side. Use it when you need a quick, private, no-account way to handle a file in the browser, or when you want an auditable open-source alternative to cloud converters, ad-heavy utility sites, and desktop apps. The page at /tools/jpg-to-png is designed for one clear job: upload or provide the input, choose only the options that matter, and download the result without creating an account or passing through a sales funnel.
Many non-PDF utilities run entirely in your browser; conversion or media operations that need backend libraries use the same isolated container model. Temporary input and output files are not used for analytics, model training, advertising profiles, or product telemetry. The public demo uses anonymous page-view analytics only; file bytes, extracted text, filenames, passwords, signatures, and generated results are outside that analytics path. If your organization needs stricter controls, you can self-host all 214 PrivaTools utilities and keep processing on your own infrastructure.
Before running JPG to PNG, confirm that the source file opens correctly and that you have permission to process it. Keep the original asset, choose the smallest output that still matches your target app, and test the result before deleting source media. For sensitive material, review the downloaded result before sharing it. For large files, give the browser time to finish the download and avoid refreshing the page mid-run. If a password, damaged upload, unsupported codec, or malformed document blocks processing, PrivaTools returns a plain-language error so you can pick the next recovery step instead of guessing.
JPG to PNG is intentionally narrow: it does one file task and hands the result back as a normal download. That makes the output easy to inspect, rename, archive, attach to email, or feed into another tool. If you need a repeatable workflow, save the page, bookmark a Pipeline recipe, or self-host the API so the same steps can run from internal scripts. The interface avoids accounts and cloud folders on purpose: the safest default for private files is to process only the current request, return the result, and leave long-term storage under your control.
JPG to PNG runs in any modern browser on Windows, macOS, Linux, Android, and iOS — there is nothing to install, no extension to add, and no desktop app to keep updated. Because the interface is a single page, you can bookmark it, send the link to a colleague, or open it on a phone and get the same result you would on a laptop. There are no watermarks stamped onto your output, no sign-in wall before the download, and no paid tier that unlocks the “real” version later — the JPG to PNG you see is the complete tool. For teams that would rather keep everything in-house, the same endpoint ships in the MIT-licensed, self-hostable build, so you can run it behind your own firewall with identical behaviour and no outbound calls. That combination — instant in the browser for individuals, fully self-hostable for organizations — is what keeps a private file genuinely private from upload to download.
PNG is lossless — every pixel of the source is preserved. Use PNG when you plan to do further editing (each JPG save degrades the image) or when you need transparency in compositing.
Yes — typically 3–10× larger, because PNG is lossless while JPG is compressed. For photos, JPG is usually a better choice unless you specifically need lossless quality.
Standard EXIF data is preserved when possible. Color profiles (sRGB, Adobe RGB) are written into the PNG header.
