Frequently Asked Questions
Common questions about merging PNG files
How do I merge PNG files while keeping transparency?
Upload your PNG files to MergeJPG, choose a layout, and download. Our tool uses the Canvas API with full alpha channel support, so all transparency in your PNG files is perfectly preserved in the merged output.
What's the difference between merging PNG and JPG?
PNG supports transparency (alpha channels) and uses lossless compression, making it ideal for logos, icons, and design assets. JPG uses lossy compression and doesn't support transparency, but produces smaller files — better for photographs. Our PNG merger preserves transparency; our JPG merger offers quality control.
Can I combine PNG files with different dimensions?
Yes. Our PNG merger automatically handles images of different sizes. Choose a layout and the tool arranges your PNG files intelligently, maintaining aspect ratios and transparency regardless of individual image dimensions.
Does merging PNG files reduce quality?
No. PNG is a lossless format, and our merger preserves every pixel exactly as-is. There is zero quality degradation — transparency, colors, and detail are all maintained perfectly in the merged output.
