Are my photos uploaded?
Photos and logos are processed in your browser. Reloading or closing the page clears your edits. Keep the page open while downloading. We count visits, imports, exports and countries. We don't collect images, filenames or watermark text, and we don't use advertising cookies. We also group usage by traffic source, entry page and preset campaign code. We don't store full referrer URLs.
How do I download all my photos?
Download one photo or the whole batch as a ZIP. Supported desktop browsers can also save directly to a folder.
Should I choose PNG or JPG?
PNG keeps transparent backgrounds. JPG turns transparent areas white. HEIC support depends on your browser. Sample images are fictional.
