Choose an image format by what the picture contains and where the file will be used. A small file is useful only if the receiving app accepts it and the result still looks right. DeskKit offers JPEG, PNG and browser-supported WebP export.
Choose JPEG for compatible photo uploads
JPEG is a useful choice for photographs when the destination supports it. DeskKit lets you adjust JPEG quality and inspect the result. Lower quality can reduce detail, especially around text and sharp edges. JPEG also removes transparency: DeskKit places transparent areas on white before exporting them as JPEG.
Choose PNG when transparent pixels matter
If a logo must sit on different background colours, test PNG. It preserves a transparent background in DeskKit’s image workflow. A photograph saved as PNG may be much larger than a JPEG version. The PNG quality control is intentionally disabled because it does not offer the same lossy quality adjustment in this tool.
Try WebP when the destination supports it
WebP is another option for browser-compatible image workflows. Test the output with the service receiving your file. A form that explicitly asks for JPG or PNG may reject WebP regardless of how small it is. DeskKit reads the actual encoded output type when assigning the downloaded extension, because browser export support can vary.
A decision checklist
- Portrait for a form: use one of the formats that the form explicitly accepts; JPEG is a candidate if listed.
- Transparent graphic: use PNG, or test WebP if accepted.
- Screenshot with fine text: inspect a PNG result first, then compare alternatives at the intended size.
- Photo for your own webpage: compare supported formats and choose after checking both visual quality and output bytes.
Changing the extension does not convert the image
Renaming photo.png to photo.jpg changes its name, not its encoding. A conversion tool must decode the source and create a new encoded file. Use DeskKit’s format selector, create the preview, and save the new result. Keep the extension that the exporter supplies.
Animation is a separate requirement
The current DeskKit canvas workflow exports a still image. Do not use it to preserve an animated greeting or moving sticker. Keep the original animation and choose an animation-aware editor for that job.
