Turn any picture into JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, SVG or a one-page PDF. HEIC from iPhones works too, and a whole folder converts in one go.
Decodes the file you drop, including HEIC, TIFF, BMP and SVG, into raw pixels and re-encodes them in the format you pick. JPEG, PNG, WebP and AVIF use the browser’s own encoder; GIF, BMP, TIFF, SVG and PDF are written by small encoders that load only when you choose them. The pixel dimensions never change, so a 4032 × 3024 photo stays 4032 × 3024 whatever the output.
A 12-megapixel HEIC from an iPhone is about 2.1 MB. Converted to JPEG at quality 90 it becomes roughly 3.6 MB, because JPEG is a less efficient codec than HEIC. The same picture as WebP at quality 90 lands near 1.9 MB, and as AVIF near 1.1 MB. Saved as PNG it balloons to 20 MB or more, since PNG stores every pixel losslessly. Converting a 300 KB transparent PNG logo to WebP typically halves it and keeps the transparency.
Use it when a site, form or app refuses the file type you have: an upload that only takes JPG, a print shop asking for TIFF, a document system that wants a single PDF page, or a Windows PC that cannot open HEIC. If the file is the right type but too big, Image Compressor is the better tool; if it is too big in pixels, use Resize Image. To combine several pictures into one multi-page document use Image to PDF, and to trace a logo into real vector paths use SVG Converter.
Quality only affects the lossy formats JPEG, WebP, AVIF and PDF; 85 to 92 is the safe range for photos. AVIF is greyed out in browsers that cannot write it (Safari and Firefox at the time of writing). Background appears when the chosen format has no transparency and fills see-through areas. GIF is limited to 256 colours, so photos come out posterised; it is meant for flat graphics. TIFF and BMP are uncompressed and can be ten times the size of the source.
Can it convert HEIC photos from an iPhone? Yes. Drop a .heic or .heif file and it is decoded in the browser, then saved as JPEG, PNG, WebP or any other format in the list. Nothing is uploaded. HEIC output is not possible because browsers have no HEVC encoder.
Does converting to SVG trace my picture into vectors? No. The pixels are embedded inside an SVG wrapper at their natural size, which is what most upload forms that insist on .svg actually need. To turn a logo into real paths use the SVG Converter tool instead.
Why is my JPEG output black where the PNG was transparent? It should not be: formats without transparency (JPEG, BMP, PDF) are flattened onto the Background colour first, white by default. Change that colour in the Convert to section if you want a different fill.
What happens to a multi-page TIFF or an animated GIF? Only the first frame or page is read, because the browser image decoder stops there. The output is a single still image.
