Supports JPEG, PNG, WebP, GIF
Convert images between popular formats including PNG, JPEG, WebP, and GIF. Adjust quality settings for optimal file size. All conversion happens in your browser.
Each image format is a tradeoff. PNG is lossless and supports transparency but produces huge files for photographs. JPEG is smaller but can't do transparency and introduces compression artifacts around sharp edges and text. WebP is roughly 30% smaller than JPEG at the same quality and supports both lossy and lossless plus transparency, but older tooling sometimes doesn't recognize it. GIF is essentially a legacy format kept alive by animations.
This converter re-encodes through the browser's Canvas and native codec APIs — the same pipelines Chrome and Safari use to render images on the web, so output is compatible everywhere those browsers are. You can adjust the quality slider for lossy formats (JPEG, WebP) to hit a target file size, or switch to PNG for graphics with text and hard edges where compression artifacts would be obvious.
The typical reason to convert is to match what a system expects: an icon pipeline that requires PNG, a CDN that penalizes non-WebP uploads, an email client that chokes on WebP, or a design handoff where the recipient's software is stuck in 2015. Converting client-side means you don't upload proprietary assets to an unknown third-party service.
- 1
Drop in your image
Upload a PNG, JPEG, WebP, or GIF. The original format and file size appear alongside the preview.
- 2
Pick the target format
Choose PNG, JPEG, or WebP and set a quality level for lossy formats. The slider shows estimated output size as you adjust it.
- 3
Download converted file
Save the re-encoded image with the new extension. Transparency is preserved when the target format supports it.
PNG to WebP migration
Cut page weight by 30% or more when swapping PNG hero images for WebP without rebuilding your asset pipeline.
JPEG to PNG for editing
Convert a photo to PNG before further manipulation so compression artifacts don't compound through multiple save cycles.
Legacy system compatibility
Re-encode WebP files to JPEG for older email clients, CMS uploaders, or internal tools that don't accept modern formats.
Transparent PNG from JPEG
Convert a JPEG to PNG when you need to composite it over a background — note you'll still need an editor to actually cut out transparency.
Will converting JPEG to PNG make it higher quality?
No. The original JPEG artifacts are baked in, and PNG will just store them in a larger file. Convert to PNG only when you need transparency or are editing further.
Why is WebP so much smaller than JPEG?
WebP uses a more efficient compression algorithm (VP8/VP9-based) that removes more perceptual redundancy than JPEG's DCT-based approach. You typically get 25–35% savings at the same visual quality.
Does the quality slider affect PNG output?
No. PNG is lossless, so the slider is ignored when PNG is selected. It only affects JPEG and WebP output.
Can I convert an animated GIF to WebP?
This converter handles static images — animated GIFs are flattened to their first frame. For animated WebP output you need a dedicated encoder like cwebp or ffmpeg.
Is my image uploaded anywhere?
No. The re-encode runs in your browser using the native Canvas API. The image never leaves your device.
