Question 1

What's the difference between JPG and PNG?

Accepted Answer

JPG uses lossy compression (smaller files, some quality loss), while PNG uses lossless compression (larger files, perfect quality). PNG also supports transparency, making it better for logos, graphics, and images that need editing.

Question 2

When should I use PNG instead of JPG?

Accepted Answer

Use PNG for logos, icons, graphics with text, images needing transparency, or when you plan to edit images later. Use JPG for photographs where file size matters more than perfect quality.

Question 3

Will PNG files be much larger than JPG?

Accepted Answer

Yes, PNG files are typically 2-5x larger than JPG because they use lossless compression. However, for graphics, logos, and images needing transparency or editing, the quality benefits outweigh the size increase.

Question 4

Can I preserve transparent backgrounds when merging?

Accepted Answer

Currently, our tool merges images with a solid background. If you need transparency, you'll need to add it after merging using image editing software.

Question 5

Is PNG better for print or web?

Accepted Answer

PNG is excellent for web use (logos, UI elements, screenshots) and suitable for print. However, for photos intended for print, high-quality JPG or TIFF formats are often preferred due to smaller file sizes.

Question 6

Will converting JPG to PNG improve quality?

Accepted Answer

No, converting from JPG to PNG won't restore lost quality from JPG compression. However, saving as PNG prevents further quality loss if you need to edit or re-save the image multiple times.

Question 7

Can I merge just 2 JPG images to PNG?

Accepted Answer

Absolutely! You can merge as few as 2 images or as many as 20. Perfect for combining logos, creating comparison images, or making simple graphics.

Question 8

Is this safe and private?

Accepted Answer

Yes, completely safe. All conversion happens in your browser - your images never leave your device. Unlike cloud-based converters that upload your files, we process everything locally for complete privacy.

Question 9

Does PNG output increase file size significantly?

Accepted Answer

Yes, PNG files are typically 2-5x larger than equivalent JPG files because PNG uses lossless compression. For example, a 500KB merged JPG might become 2MB as PNG. Use PNG only when you need transparency support or absolute quality preservation. For most web use and sharing, JPG is more practical.

Question 10

Can I preserve transparency when merging PNGs?

Accepted Answer

Yes! When you merge PNG images with transparent backgrounds, the tool preserves transparency in the final output. This is perfect for creating layered designs, logos, or graphics where you need a transparent background. The spacing between images will also be transparent.

Question 11

Which format is better for web use: PNG or JPG?

Accepted Answer

For merged photos and images without transparency, use JPG format - it's 70-80% smaller and loads faster on websites. Use PNG only when you need: (1) transparent backgrounds, (2) text or graphics with sharp edges, or (3) images you'll edit later. For social media and general web sharing, JPG is almost always the better choice.
