Frequently Asked Questions
Why should I convert JPG to PNG?
PNG is a lossless image format. Converting to PNG allows you to edit or save graphics, logos, screenshots, and text graphics repeatedly without introducing JPEG compression artifacts or color smearing.
Does converting JPG to PNG create transparency?
No. Original JPG files do not possess an alpha transparency channel. The resulting PNG retains the exact pixel colors of the original JPG with full lossless color depth.
Can I convert multiple JPG images at once?
Yes. SizeSnap lets you select or drop multiple JPG photos, convert all of them simultaneously in your browser, and download them individually or packed in a convenient ZIP file.
Are my private photos uploaded to a cloud server?
No. All image processing takes place completely within your web browser using HTML5 Canvas technology. No images are sent over the network or saved on remote servers.
