PNG to JPG Converter – Convert PNG Images to JPG Online Free

About PNG to JPG Converter

The PNG to JPG Converter lets you upload one or multiple PNG images and convert them into JPG (JPEG) format. After conversion, the tool lists each converted image with file details and provides options to download files individually or download all converted images together in a single ZIP file.

What Is a PNG File?

PNG (Portable Network Graphics) is an image format known for lossless quality and support for transparency (alpha channel). PNG images are commonly used for graphics, UI assets, and images where transparent backgrounds are needed.

What Is a JPG File?

JPG (or JPEG) is a widely used image format that saves images using compression. JPG is commonly used for photos and web images where smaller file size is preferred.

What This Tool Does

This tool converts uploaded PNG images into JPG format while keeping the original image dimensions. Since JPG does not support transparency, the tool handles transparent PNG images by converting them into a standard JPG-friendly format.

Key Features

Multiple PNG Upload Support

• Upload multiple PNG files at once.

• Upload using drag-and-drop or file selection.

• Filters and accepts only PNG files.

Automatic PNG Validation

• If a file is not PNG, it is ignored.

• If no valid PNG files are provided, the tool shows an alert asking for PNG files only.

PNG Transparency Handling (Alpha Channel Support)

If a PNG has transparency (e.g., RGBA or LA mode), the tool:

• Creates a solid background

• Merges the PNG onto it

• Converts the final image into a JPG-compatible format

This ensures conversion works properly even for transparent PNG images.

JPG Conversion with Set Quality

• Converted images are saved as JPG using a fixed quality setting (quality=90).

• Each converted image is given a unique name to avoid overwriting.

Results Display With File Details

After conversion, the results list shows:

• Converted file name

• File size

• Image dimensions (width × height)

• Output format (JPEG)

Files that fail conversion are displayed with an error message instead.

Download Options

• Download each converted JPG individually using a download button.

• Download all converted JPG images together as a ZIP file.

How the Tool Works

Step 1: Upload PNG Images

You add PNG files via drag-and-drop or file input.

Step 2: Temporary Processing

Uploaded files are kept temporarily for conversion.

Step 3: Convert PNG to JPG

For each uploaded PNG:

• The tool checks file availability

• Opens the image and converts it into a JPG-compatible format

• Saves a new JPG output file

Step 4: Show Converted Files

Converted images appear in the results section, and the page scrolls down automatically to display them.

Automatic File Cleanup

For privacy and cleanup:

• Uploaded PNG files are automatically deleted when you leave the page.

• If you click the Clear button, uploaded temporary files are also removed.

This prevents temporary uploads from staying stored unnecessarily.

User Interface Experience

• Drag-and-drop upload area with highlight effect

• Upload list showing file name and file size

• Remove icon to delete selected files from the upload list

• “Uploading…” and “Converting…” button states

• Results section appears only after conversion

Error Handling

The tool handles:

• Uploading invalid file types

• Missing files during conversion

• Conversion failures per file

• Network request errors

If a file fails, it shows an error entry but continues processing the rest.
