How to Convert PNG, JPG and WebP Images

Image formats serve different purposes. JPG is compact for photographs, PNG preserves sharp graphics and transparency, and WebP can provide efficient web images. Conversion changes the encoding but cannot improve a poor source image.

This guide explains a careful workflow using Convert Image. Work with a copy when the source matters, and always inspect the output before submitting, sharing, or deleting anything.

Before you start

Use the final source file, close it in other applications, and confirm that you are authorised to process its contents. A stable connection helps with uploads, but the quality of the result still depends on the source. Password-protected or severely damaged files may need attention before processing.

Step-by-step workflow

1. Identify where the converted image will be used.
2. Choose PNG for lossless graphics or transparency, JPG for broad photo compatibility, or WebP for supported web use.
3. Upload the source to Convert Image.
4. Select the output format and process it.
5. Download and compare transparency, colour, sharpness, and size.

Quality checks

Do not judge a document only from a successful download message. Open the result in a PDF reader and check these points:

• Transparent backgrounds behave as expected.
• Text and line art do not show distracting artefacts.
• The destination application supports the format.

Practical notes

• Converting JPG to PNG does not restore quality previously lost.
• Keep the highest-quality source as the master for future conversions.

Privacy and file handling

Only upload documents you are permitted to process. XPPDF uses short-lived processing storage; signed-in users can keep eligible workspace files for up to three days, while guest jobs have a shorter retention period. Download important results promptly and remove files you no longer need from your workspace.

Frequently asked questions

Does the process change my original file?

The tool creates a new output. Your local original remains unchanged unless you deliberately replace it after downloading.

Should I check the output before using it?

Yes. Check page count, readability, order, and any critical names, totals, dates, or signatures. Automated processing cannot understand the business meaning of every document.

Can I continue with another PDF task?

Yes. After checking the result, use the workspace actions or visit all XPPDF tools to continue with a relevant task. Choose only the operations you actually need so that quality is not reduced by unnecessary repeated processing.

Final checklist

• Keep the original until the result is accepted.
• Open the downloaded output rather than relying on its filename.
• Confirm the file meets the recipient's format and size rules.
• Protect confidential documents after download.
