PNG is a lossless format — every pixel is encoded exactly, which is great for logos, screenshots, and images with hard edges, but terrible for file size. A photo saved as PNG can be 10× larger than the same photo as JPEG or WebP with no visible quality difference.

For that reason, ImgSolve defaults PNG compression to WebP output. WebP supports transparency (unlike JPEG), matches or beats PNG on file size for most images, and is supported by every modern browser. If you specifically need PNG output — for a tool or platform that doesn't accept WebP — you can keep the format; the tool will re-encode the PNG through a canvas, which sometimes helps by dropping redundant metadata, but savings will be modest.

Everything runs in your browser. There is no upload endpoint, and EXIF-style metadata is stripped automatically during re-encoding.

FAQ

Why is my compressed PNG not much smaller?+

PNG is lossless — the only way to significantly shrink it is to switch to a lossy format like WebP or JPEG. If you need PNG output for compatibility, savings will be small (usually 5–15%). On Safari, WebP encoding isn't supported and the tool falls back to JPEG.

Will transparency survive?+

Yes if you choose PNG or WebP output. Choosing JPEG will fill transparent areas with the background color you pick.

Are my images uploaded to a server?+

No — never. Every conversion and compression happens directly in your browser using JavaScript and the Canvas API. ImgSolve does not run an upload endpoint; there is no server that could receive your files even if we wanted one.

Does ImgSolve remove EXIF data like GPS location?+

Yes, automatically. Re-encoding an image through a canvas strips all EXIF metadata — GPS coordinates, camera model, timestamps, and any other embedded tags — as a side effect of how canvases work. The output file contains only the pixels.
