What Convert from JPG helps you do

Convert JPG photos to PNG or WebP in a private batch. PNG gives you lossless output for editing, while WebP is the smaller modern format for the web. The source pixels are preserved as far as the original JPEG allows, and a background color fills any area that needs to become opaque.

The conversion happens locally in your browser. Files are not sent to Haivix.

How it works

These tools decode the image in your browser, draw it onto a canvas, apply the change, and encode a new file. Nothing is uploaded, so the result depends on the browser's own decoders and encoders rather than a server library. Re-encoding always creates a new file: metadata such as EXIF, GPS and color profiles is generally dropped, and JPEG or WebP output loses a little quality on every save. Canvas work is capped at roughly 36 megapixels, so very large images may be refused rather than processed slowly. Browsers normally apply EXIF orientation when decoding, so a phone photo usually appears upright before any rotation is applied.

How to use Convert from JPG

Drop the JPG images to convert.
Choose PNG or WebP as the target.
Set the quality for WebP, or leave the default.
Convert and download the results.

When to use it

Turn a photo into PNG before adding transparency.
Create WebP versions to reduce page weight.
Convert camera JPGs into an editable lossless format.
Prepare images for a tool that rejects JPEG.
Move screenshots of photos into a lossless workflow.
Produce a WebP set for a responsive image tag.

When not to use it

Do not expect PNG to restore detail the JPEG already discarded.
Do not convert a photo to PNG when file size is the priority.
Do not use WebP for a system that only accepts JPG or PNG.

Example

A JPG photo converted to PNG keeps its appearance but can now be edited or masked without further quality loss. The PNG is often several times larger than the original JPEG. A WebP export at quality 90 is usually smaller than the PNG, but it is still a lossy re-encode if the quality is below 100.

What you can do with Convert from JPG

Accept JPG images as a batch.
Convert to PNG or WebP.
Set WebP quality when a lossy target is chosen.
Fill transparent areas with a chosen background.
Download individually or as a ZIP.
Run the conversion locally in the browser.

Example: pick the format for the job, then check the result

Keep the original. Every tool downloads a new file, and repeated conversion between lossy formats compounds artifacts.

Choose the format by purpose: PNG for sharp edges, text and transparency; JPEG for photographs; WebP when file size matters on the web.

Check transparency before converting to JPEG. Alpha is flattened onto a background color, and the choice is permanent in the output.

Look at the output at 100 percent. Smoothing, sharpening and watermark placement are easier to judge at full size than in a small preview.

For a batch, check the ZIP contents and file count. A single failed image is reported separately and does not stop the rest.

Note the output dimensions and file size. A larger pixel count does not always mean a better result, and a large PNG can be slower to load than a smaller JPEG.

What to know before you start

Converting from lossy JPG to PNG does not recover any quality that was already lost.
PNG output is often much larger than the source JPG.
The tool accepts JPEG input only, so PNG and WebP sources are not part of this batch.
Metadata such as EXIF and GPS is not carried into the output.

Common mistakes

Believing a JPG-to-PNG conversion improves quality.
Using PNG for a photo-heavy gallery and bloating the page.
Assuming every browser or CMS accepts WebP.
Reconverting a JPEG many times and adding artifacts.

Troubleshooting

If the PNG is huge, the source contains a lot of high-frequency detail; WebP may be a better target.

If transparent areas look black, a background color was not set.

If a file is skipped, confirm it is actually JPEG and not a renamed PNG.

If the ZIP is empty, no files were accepted by the drop area.
