What is a PNG file?
PNG is a lossless image format: it keeps every pixel exactly as it is and can have a transparent background. That makes it right for logos, screenshots and print files, but a photo saved as a PNG is several times larger than the same photo as a JPG.
Why JPG?
Every phone, computer, website, email program and printer opens a JPG. At 90% quality and above a JPG of a photo looks the same as the original, at a fraction of a PNG’s size. It is the safe choice whenever you do not know what the other side can open.
Nothing is uploaded
Converters that upload your photos keep a copy on someone else’s server, at least for a while. This one does the work in your browser, on your own device, so private photos stay private. The pictures are also saved fresh, so the camera details and GPS position phones write into every photo are not copied into the new files.
Printing the photo
A 12 MP iPhone photo (4032 × 3024 pixels) prints sharp up to about 13 × 10 inches at 300 DPI, and about twice that as a poster seen from a step back. The print size calculator works it out for any picture. Then put it on a poster or a mug.

What is a PNG file?
PNG is a lossless image format: it keeps every pixel exactly as it is and can have a transparent background. That makes it right for logos, screenshots and print files, but a photo saved as a PNG is several times larger than the same photo as a JPG.
Why convert a PNG to JPG?
To make it smaller. A photo or a detailed picture saved as a PNG is often three to five times larger than as a JPG that looks the same, which matters for email, websites and upload limits. Keep the PNG for logos and print files with a transparent background.
Does converting to JPG lose quality?
A little, as every JPG does. At the 92% quality the converter starts at, the change cannot be seen in a photo. Raise it to 100% for the most detail, or lower it for a smaller file. See-through parts become white, as a JPG cannot be transparent.
Are my files uploaded?
No. The converter runs in your browser: files are opened and saved on your own device and never sent to SlapMake or anyone else.
How many files can I convert at once?
Up to 30 at a time, each up to 50 MB and 100 megapixels. Camera data and GPS position are not copied into the new files. A picture larger than a phone browser can hold is made as large as it allows, and the page says so.
