JPG or PNG for your collage download?
Choose for the contents
JPG and PNG can both contain your collage. JPG is often a convenient smaller file for photography. PNG preserves sharp graphic details without JPEG-style compression artifacts. Actual sizes depend on the images and canvas.
Download both and compare locally if you are unsure. Neither adds a watermark, and source photos are not uploaded to create either format.
JPG suits photo-heavy work
JPG reduces size through lossy compression. At a good quality level photos can still look clear. Inspect high-contrast edges and small lettering, where artifacts are easier to notice.
Worked example: download a four-photo travel collage as JPG at Original size. Open it on your phone and inspect faces and the caption. If it looks clear at the intended size, a larger file may offer little practical benefit.
PNG preserves crisp pixels
PNG losslessly compresses the finished pixel data. It can suit prominent text, clean borders or flat-colour graphics. A photographic PNG may be considerably larger than a JPG at the same dimensions.
Changing formats cannot invent missing source detail. If a small photo looks soft when enlarged, use a better original or place it in a smaller slot. Avoid repeated lossy resaves through other editors.
Match dimensions to the job
Original size uses the preset dimensions. A 1080×1920 Story becomes 2160×3840 at 2×. Jarvis caps the longest edge and resizes input photos for manageable editing, so larger exports should be inspected rather than assumed to retain unlimited original detail.
Social apps may recompress an uploaded image. Check the final destination, then keep the downloaded collage as your finished copy.
