JPG to PNG Converter

Convert JPG or JPEG images to PNG format with full lossless quality. PNG is the format of choice when you need transparency support, lossless editing, or when working with graphics, logos, and screenshots that need to remain pixel-perfect. All conversion happens in your browser — no files leave your device.

PNG supports transparent backgrounds and lossless compression. Converting from JPG to PNG preserves all visible pixels, though PNG files will be larger.

How to Use JPG to PNG Converter

  1. 1

    Upload your JPG

    Click the upload area or drag and drop your JPG or JPEG image. You can also upload WebP, BMP, or other formats to convert them to PNG.

  2. 2

    Review the preview

    The original image is displayed immediately. PNG output is lossless so what you see is exactly what you will get — no quality controls needed.

  3. 3

    Convert

    Click Convert. The browser decodes the JPG and re-encodes it as a lossless PNG. Processing is instant for most images.

  4. 4

    Download

    Download the PNG file. Note that PNG files are typically larger than JPG because they use lossless compression — this is normal and expected.

When to Use This Tool

Preparing images for editing
Every time you save a JPG, quality is lost. Convert to PNG before editing in any image editor so you can save repeatedly without accumulating quality degradation.
Background removal
PNG supports transparency, JPG does not. Convert to PNG first, then use the Background Remover to get a transparent cutout of your subject.
Screenshots and screen captures
Screenshots often look blurry when saved as JPG due to compression artefacts around text. Convert or save screenshots as PNG for crisp, readable text.
Logos and graphics with text
JPG compression creates visible artefacts around sharp edges and text. Convert logos and text-heavy graphics to PNG to preserve clean, sharp edges.
Long-term archiving
PNG is a lossless format — the file stored is the file you get back, always. For images you want to archive without any quality degradation over time, PNG is the right choice.

About JPG to PNG Converter

The JPG to PNG Converter converts JPEG images to PNG format, giving you a lossless copy of your photo that supports transparency and can be re-saved without quality degradation. While the conversion cannot restore quality lost in the original JPG compression, it "freezes" the current quality and prevents further loss during subsequent edits and saves.

JPG to PNG conversion is needed for:

  • Converting a JPG before removing the background — PNG supports transparency, JPG does not
  • Converting logos or graphics that were mistakenly saved as JPG to the correct lossless format
  • Preparing images for editing workflows where you'll be saving multiple times
  • Screenshots that look blurry as JPG due to compression artifacts around text
  • Archiving images in a format that will not degrade over time with repeated opens and saves

The conversion decodes the JPEG image data using the browser's native JPEG decoder (which handles the full JFIF/EXIF specification) and renders it to an HTML5 Canvas element. The Canvas then encodes the pixel data as a PNG using lossless DEFLATE compression. Because PNG is lossless, every pixel value is preserved exactly as decoded from the JPG — the resulting PNG faithfully represents the JPG content at the point of conversion. The PNG file size will typically be 2–5× larger than the JPG because PNG stores uncompressed color data rather than discarding it.

Input formats: JPG, JPEG (also accepts WebP, BMP for conversion to PNG). Output: PNG with lossless compression. Transparency: the PNG will have no alpha channel since JPEG has no transparency — the background remains solid. Max file size: 20 MB. Batch support: convert multiple JPG files at once.

All conversion runs in your browser — images are never uploaded to any server. For adding a transparent background after converting, use the Background Remover. If file size is a concern, the Image Compressor can reduce PNG file size significantly using palette optimization.

Pro Tips for JPG to PNG Converter

1

Convert to PNG before using the Background Remover — the AI works on PNG output with full alpha channel support, whereas JPG doesn't support transparency at all.

2

For screenshots with text, always save as PNG rather than JPG — JPEG compression creates visible artifacts around sharp text edges that PNG avoids completely.

3

If you're working with a JPG that needs multiple rounds of editing, convert to PNG first — each JPG save loses quality, while PNG saves are lossless.

4

After converting a JPG logo to PNG, check the edges at 200% zoom — JPEG artifacts around edges may need cleaning with the eraser tool in an image editor before using the PNG.

Frequently Asked Questions

Does converting JPG to PNG improve quality?+
No. Converting a JPG to PNG preserves the quality exactly as it is in the JPG — it does not add back quality that was lost when the JPG was originally created. What PNG does is prevent any further quality loss during subsequent saves. Think of it as freezing the current quality rather than improving it.
Will my JPG image become transparent after converting to PNG?+
No. The image content stays the same — only the format changes. The solid background in your JPG will remain solid in the PNG output. To make an area transparent, use the Background Remover tool after converting.
Why is the PNG file larger than the original JPG?+
JPG uses lossy compression that discards some data to achieve very small file sizes. PNG uses lossless compression that stores all pixel data exactly. For photographs, PNG files are typically 3–10x larger than the equivalent JPG. This is expected and is the trade-off for lossless quality.
When should I use PNG instead of JPG?+
Use PNG when: (1) you need transparency, (2) you will edit and re-save the image multiple times, (3) the image contains text or sharp lines (logos, screenshots), or (4) you are archiving files for long-term storage. Use JPG for photographs destined for web or email where file size matters most.
Can I convert multiple JPG files to PNG at once?+
Yes — drop multiple JPG files into the upload area and each is converted independently. Download them individually or use the Download All button.
Can I convert the PNG back to JPG later?+
Yes — use the PNG to JPG converter tool. For best results, keep the original source file and only convert to JPG as the final step for publishing.
