Image Converter
Convert between JPG, PNG, and WebP.
Runs entirely in your browser — nothing you enter is uploaded or sent to a server.
Converting to JPG or WebP re-encodes the picture (lossy), and moving to a format without transparency fills any see-through areas with white. It all happens in your browser — your image isn't uploaded. Read our full disclaimer.
About this tool
Different places want different image formats: JPG is accepted almost everywhere, PNG keeps sharp edges and transparency, and WebP is usually the smallest for the same quality. This tool re-encodes your image from one to another, with a quality slider for the lossy formats. Drop an image in, choose a target, and download — no upload and no sign-in.
Example
A 2.5 MB PNG screenshot converted to WebP at quality 85 often drops to a few hundred KB while looking the same — ideal for the web.

Frequently asked questions
Which format gives the smallest file?
Usually WebP — similar visual quality to JPG at a smaller size, with transparency support as a bonus. JPG is the safest for maximum compatibility; PNG is best for graphics or anything with transparency you must keep.
Why did my transparent PNG get a white background as a JPG?
JPG has no transparency channel, so those pixels have to become a solid colour — we use white. Convert to PNG or WebP instead if you need to keep transparency.
Does converting lose quality?
Converting to PNG is lossless. Converting to JPG or WebP re-encodes and is lossy, so use the quality slider — 80 to 90 is usually indistinguishable from the original.
Can it convert HEIC photos from my iPhone?
Not yet — HEIC needs a decoder we haven't added. For now, convert HEIC to JPG on your device first, then bring that into this tool.
