JPG to PNG Converter
Drop JPG files, get PNG back — 100% in your browser. No uploads, no accounts, no limits. Batch convert, optional resize, orientation fixed.

PNG is lossless, so the output is usually 3–8× larger than the JPG — that is normal. Converting cannot restore detail JPEG already threw away, and JPG has no transparency, so the PNG has no alpha channel.

How to convert JPG to PNG without uploading it
- Drop your JPG files above — or paste one straight from your clipboard. You can add up to 20 at once.
- Optionally resize — tick the resize box to cap the width (1920 px by default), which also keeps the PNG much smaller. Leave it off to keep the original size.
- Download each file, or grab everything as one ZIP. Your originals are untouched and your file data never leaves your device.
Why convert JPG to PNG at all?
JPG is small because it throws detail away — fine for sharing, bad for editing. PNG is lossless: once your image is a PNG, every further edit and save keeps exactly what is there, with no more quality loss. Some design tools, print workflows, and upload forms also prefer or require PNG. Converting is the right move when you are about to edit a photo repeatedly, or when a tool will not accept a JPG.
Honest limitations
- PNGs are much larger — typically 3–8× the JPG for a photo. That is normal, not a defect: PNG stores every pixel exactly. The tool shows the real size on each file.
- Converting cannot restore detail — JPEG compression already threw detail away, and a PNG wrapper cannot bring it back. The PNG keeps exactly the quality the JPG had.
- JPG has no transparency — so the PNG has no alpha channel either. If you need a transparent background, start from a PNG.
- EXIF metadata is dropped on re-encode. Orientation is applied from the EXIF data, so photos still come out upright.
- Estimates are estimates — the size shown while converting is a rough model; the real size is shown once conversion finishes.
Frequently asked questions
How can I convert JPG to PNG without uploading it anywhere?
This converter runs entirely in your browser: it decodes your JPG with your browser's built-in support and re-encodes it as PNG on a canvas. Your file data never leaves your device — the only third-party requests are the site's own analytics, which load at page open and never see your files. Verify it in the Network tab while it works.
Why is my PNG so much larger than the original JPG?
PNG is lossless: it stores every pixel exactly, while JPG threw detail away to get small. A photo PNG is typically 3–8 times larger than the same image as JPG. That is normal, not a defect — the tool tells you the size on each file instead of hiding it.
Does converting JPG to PNG improve quality?
No. Converting to PNG cannot restore detail that JPEG compression already threw away — it only stops further loss. A JPG saved as PNG keeps exactly the quality the JPG had, in a lossless wrapper. Keep the original JPG if you need the smallest file.
Will my PNG have a transparent background?
No. JPG has no transparency, so there is no alpha channel to carry over — the PNG is fully opaque. If you need a transparent background, start from a PNG, not a JPG.
Does converting strip EXIF data or fix photo orientation?
Re-encoding drops EXIF metadata (camera settings, location) — keep the original if you need it. Orientation is applied from the photo's EXIF data, so rotated photos come out upright.
Is there a file size or daily limit?
No daily limit, no account. A 25 MB cap per file, a 50 megapixel cap per image, and 20 files per batch apply, because browsers cannot safely hold larger images in memory.
Can I resize my images while converting?
Yes — tick the resize option and set a maximum width (1920 px by default). Images wider than that are scaled down keeping their aspect ratio; smaller images are never upscaled. Resizing also makes the PNG much smaller, because a smaller image stores fewer pixels.
How do I verify my files really never upload?
Open developer tools (F12), go to the Network tab, then convert a file. Your file data never leaves your device — the only third-party requests are the site's own analytics, which load at page open and never see your files. The live counter above shows the same number.
