Your image is decoded and re-encoded on this device. No upload request is made.
PNG preserves transparent pixels and uses lossless encoding.

Browse all image toolsJPG and JPEG are two names for the same image format. PNG is a different format with lossless compression and broad support in graphics, document, presentation, and web software. Changing the filename from .jpg to .png does not perform a conversion because applications inspect the encoded bytes, not only the extension. This tool decodes the JPEG pixels and writes a real PNG file at the original dimensions. The work happens in the current browser tab, so a personal photo, client image, or unpublished design is not transmitted to a conversion service. The output is measured before download, making one important trade-off visible: converting a photograph to PNG often increases file size even though it prevents another lossy JPEG encoding step.
A screenshot or diagram saved as JPEG can accumulate more edge damage each time it is edited and saved again. Converting the current pixels to PNG gives later raster edits a lossless save format, although damage already present remains visible.
Some design systems, slide templates, and application portals validate the actual file signature. The generated PNG contains PNG bytes, unlike a JPEG that was merely renamed in the file manager.
Both filename endings describe JPEG. Searches and aliases resolve to this single canonical owner, while the picker accepts either extension and produces the same PNG workflow.
No. They are different filename extensions for the same JPEG image format. The shorter .jpg form became common on systems that historically limited extensions to three characters.
It will not recover lost detail. The PNG preserves the JPEG's currently decoded pixels without adding another lossy encoding pass, but existing JPEG artifacts remain.
No. JPEG does not contain transparency information, so the converted PNG remains opaque. Background removal is a separate image-editing operation.
PNG compression is lossless and is less efficient for complex photographs. JPEG achieves smaller photographic files by discarding visual information, while PNG retains every converted pixel exactly.
No. Browser image and canvas APIs perform the conversion locally. The result is exposed through a temporary object URL and no file body is sent to Shard Tools.
Convert PNG to JPG locally in your browser. Transparent pixels are placed on white, dimensions stay unchanged, and the image is never uploaded.
Turn a WebP image into a compatible JPG directly in your browser. Preview dimensions and file size before downloading.
Hit a hard 100KB upload limit exactly. Binary-search compression runs in your browser, so the photo never leaves your device. JPG, PNG, and WebP.
Create an exact 200×200 JPG, PNG, or WebP in your browser. Crop to fill or fit with a background, verify the real dimensions, and download without uploading your image.
Re-encode a JPG photo as WebP in your browser to cut page weight. Compare the before and after byte counts before you download.
Turn a GIF into a JPG your software will accept. Runs in your browser with nothing uploaded.
Convert a BMP to JPG in your browser. BMP files are uncompressed, so the saving is usually enormous.
Convert an ICO icon to JPG in your browser. Transparent areas become white, as JPEG requires.
