🧩

Every pixel from your JPG is preserved in a lossless PNG without any recompression.

⚡

No upload, no queue, no wait. The PNG is ready the moment your JPG finishes loading.

🖼️

The output keeps the original width, height, and sharpness of your source image.

🔒

Local Device Privacy

Conversion runs entirely in your browser. Your photos are never uploaded or seen by any server.

How to Use the JPG to PNG Converter

  1. Drag and drop a JPG or JPEG into the upload area, or click browse files to select one from your device.
  2. The lossless PNG preview appears automatically as soon as the file loads.
  3. Review the preview and the size statistics, including the new PNG size and dimensions.
  4. Click Download PNG to save the converted file, or click Reset to start over.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

Many online converters ask you to upload your photo before processing. That creates privacy risk for personal or work images. TinyToolzz takes a different approach: the JPG to PNG conversion happens entirely on your device with the HTML5 Canvas API.

The preview and the final PNG file are both produced in your browser memory. Nothing is sent over the network, stored, logged, or shared. When you leave the page or click Reset, the image data is released from memory.

Frequently Asked Questions

Is converting JPG to PNG lossless?
PNG is a lossless format, so the converted file keeps every pixel of the decoded JPG exactly. Keep in mind that the JPG was already compressed with loss when it was created, so converting cannot restore detail that was discarded during the original JPEG save.
Why is my PNG file larger than the JPG?
JPEG is a lossy format designed to make photos small, while PNG stores every pixel without loss and is usually larger. This is expected and is the trade-off for keeping the image fully lossless.
Are my photos uploaded to a server when I convert them?
No. The JPG to PNG tool runs entirely in your browser using the HTML5 Canvas and FileReader APIs. Your image is read from your device, converted locally, and is never transmitted, stored, or recorded on any remote server.
When should I use PNG instead of JPG?
Use PNG for images with text, logos, or graphics that need sharp edges and lossless quality, or when you need transparency. Use JPG for photographs where a smaller file size matters more than pixel-perfect detail.
Does converting remove EXIF metadata from my photo?
Yes. Re-encoding the image on a canvas strips EXIF data such as camera model, GPS location, and capture settings from the output PNG. The visual orientation from the original JPG is applied to the pixels, so the result matches what you see.
What file size and resolution limits apply?
Files up to 50 MB are supported, and each side of the output is capped at 10,000 pixels to protect your browser from running out of memory. There is no limit on how many images you can convert, and the tool is free with no sign-up.
