Image compressor and converter

Make photos smaller or switch between JPG, PNG and WebP. With "Keep original type", GIF and BMP files are saved as JPG.

PNG is lossless, so the quality slider does not change PNG size. To shrink a PNG, lower the max width or switch to WebP or JPG.

Images to PDF

Combine photos or scans into one PDF, one image per page. Reorder them before you create the file.

Paste JSON to check it, make it readable, or shrink it to a single line.
