PicUplift — Local Image Tools

Convert HEIC to JPG/PNG, WebP to PNG, and compress images locally. Free offline side panel with batch and ZIP downloads.

Convert and compress images directly on your device with PicUplift. Click the toolbar icon to open its side panel, choose a tool and your files, adjust the settings and save the results. For long batches, use Open in tab before choosing files to create an independent workspace. All processing libraries are bundled in the extension, so conversion works offline. Four everyday image tools: HEIC to JPG: convert HEIC/HEIF photos with adjustable JPG quality and dimensions. Default quality is 90%. HEIC to PNG: export decoded HEIC/HEIF pixels with lossless PNG encoding and optional resizing. WebP to PNG: create static PNG images while preserving transparency. Image compression: process JPG, PNG and WebP with quality, output format and dimension controls. Default quality is 80%; automatic format keeps JPG as JPG and converts PNG to WebP. Batch processing includes progress, cancel, per-file previews and real before/after byte counts. Download successful results individually or together in a ZIP. Failed files have their own error message, and the rest of the batch continues. If a result is larger, you can download the unchanged original instead. English and Simplified Chinese are available. PicUplift requests only the sidePanel permission needed to display its side panel. It has no host or tab-reading permissions and does not read browsing history or other tabs. It includes no analytics, advertising, remote code or network requests. Selected files and converted results stay in the workspace's memory during use. Chrome manages saved downloads. Keep the panel or tab workspace open while processing. Closing, refreshing or switching tools can discard that workspace's files/results. Open in tab creates a fresh independent workspace and does not copy existing files/results. Open another tool link in a new tab to preserve the current batch. The tools are free with no imposed file-size or conversion-count cap. Practical capacity depends on your device, browser and ZIP format. Compression savings are not guaranteed. Static output only: animated WebP/PNG uses the first frame; multi-image HEIC uses its primary image. Converted outputs do not copy camera metadata or Live Photo video. Color/HDR appearance and uncommon HEIC variants may differ or be unsupported. PNG encoding is lossless, while decoding, color handling and resizing may still affect pixels.
