Convert images between JPG, PNG & WebP
Switch formats in seconds without uploading anything. Pick any output below, or jump straight to a preconfigured converter for the most common pairs. Everything runs on your device with canvas encoding.
Universal image converter
Upload once, pick JPG, PNG, or WebP, tune quality, download.

Up to 10 files · JPEG, PNG, WebP, HEIC, GIF, BMP or AVIF up to 50MB each — never uploaded
85–92% looks identical to the original for most photos. Applies to new conversions.
Private by design: conversion runs with canvas encoding on your device. Converting to JPEG flattens transparency onto a white background, and re-encoding always strips EXIF metadata.

JPG vs PNG vs WebP vs HEIC — which to pick
Every format is a different trade-off between size, quality, and compatibility. Photos with smooth gradients compress best as JPG or WebP; graphics with sharp edges and transparency need PNG or WebP; iPhone originals arrive as HEIC and usually need converting before anything else can open them. The table below summarizes the decision in one glance.
JPG — universal compatibility
Opens everywhere: portals, email, printers, office software, and every phone from the last twenty years. Lossy compression keeps photos small. No transparency. Default choice when you are unsure where the file will end up.
PNG — lossless and transparent
Preserves every pixel exactly and supports alpha transparency, which makes it ideal for logos, icons, and screenshots with text. The price is size: photographic PNGs are often 5–10x larger than the same image as JPG.
WebP — smallest for the web
Google's modern codec is typically 25–35% smaller than JPG at equal quality, supports transparency, and renders in all current browsers. Best for site images, avatars, and thumbnails where you control the destination.
HEIC — iPhone default, convert it
Apple's High Efficiency format stores excellent quality in tiny files, but Windows apps, upload forms, and many web tools reject it. Convert HEIC to JPG the moment you need to share, print, or upload.
Quality settings that actually work
The quality slider is the single biggest lever on file size. For JPG and WebP output, 85–92% is visually identical to the original for almost every photo — differences only appear when pixel-peeping at 200% zoom. Each 5-point drop below 80% roughly halves the remaining quality headroom, so move in small steps: convert once at 90%, check the result, and only go lower if the file is still too big. Avoid converting the same file twice (JPG → WebP → JPG), because every lossy generation discards fresh detail. When transparency matters, choose PNG or WebP instead of JPG — flattening an alpha channel onto white is irreversible, so keep a transparent master copy before you convert.
How conversion works
1
Choose a file
Drop a JPEG, PNG, WebP, GIF, BMP, or AVIF file up to 50MB.
2
Pick a format
Select JPG, PNG, or WebP and set quality (85–92% is the sweet spot).
3
Download
Canvas re-encodes the pixels locally and you save the new file.
PixelShrink never uploads your files: conversion happens entirely in your browser, and re-encoding strips EXIF metadata by default.
Frequently asked questions
Which image format should I choose?
Use JPG for photos where small size matters, PNG for screenshots or graphics that need transparency or pixel-perfect edges, and WebP when you want the smallest file for the web and your audience uses modern browsers.
Does converting change image quality?
Converting between lossy formats (JPG, WebP) re-encodes pixels, so a small quality loss is possible — keep quality at 85% or higher to stay visually identical. Converting to PNG is always lossless but usually produces larger files.
What happens to transparency when converting to JPG?
JPEG has no alpha channel, so transparent areas are flattened onto a white background during conversion. If you need transparency, convert to PNG or WebP instead.
Are my images uploaded anywhere?
No. Every conversion runs locally in your browser with canvas encoding. Files never leave your device, and re-encoding strips EXIF metadata automatically.
Can I convert HEIC photos from my iPhone?
Yes. Drop a .heic or .heif file into the converter and it is decoded on your device into a JPEG-compatible image, then re-encoded to JPG, PNG, or WebP. iPhones shoot HEIC by default because it stores the same quality in roughly half the bytes of JPEG — but many portals, email clients, and Windows apps still reject it, so converting to JPG is the fastest fix.
Which quality setting should I use?
For JPG and WebP output, 85–92% is the sweet spot: visually identical to the original for photos at a fraction of the size. Use 90%+ for images with text overlays or images you plan to edit further, and 75–80% for thumbnails where size matters more than perfection. PNG output is always lossless, so no quality setting applies.
