Upload Rescue

網站說檔案太大？在 Chrome 本機處理圖片、支援的 PDF 與 macOS HEIC，不上傳檔案內容。

Upload Rescue prepares supported files locally in Chrome before you upload them to a website. The extension reads only files you explicitly select and keeps their content, outputs, history, and processing records in browser-managed local storage. It does not send image or PDF content to Upload Rescue, Cloudflare, or Polar. Only user-initiated Pro activation or Verify sends license authentication data to the dedicated license service over HTTPS. IMAGE PREPARATION - Compress static JPG, PNG, and WebP images toward a selected Target size. - Convert between JPG, PNG, and WebP while keeping the original dimensions. - Use 500 KB, 1 MB, 2 MB, or 5 MB presets, or enter a custom Target from 10 KB through 100 MB. - Private image metadata is removed by default. For compatible JPG-to-JPG output, users may retain an allowlist of camera, exposure, and optics fields; GPS, serials, notes, thumbnails, unknown fields, and editing history remain removed. - On macOS, convert a supported HEIC or HEIF primary image to JPG, PNG, or WebP within the accepted local safety envelope. - Windows v0.5 does not support HEIC or HEIF. JPG, PNG, WebP, and PDF features remain available on Windows. SAFE PDF COMPRESSION - Compress supported PDFs without converting whole pages to images. - Preserve selectable text, vectors, page geometry, links, fonts, annotations, and supported static form fields when validation passes. - Reject encrypted, signed, damaged, or otherwise unsupported PDFs, including documents with embedded files or unsupported dynamic content. - A PDF result is offered only when it passes local validation and is meaningfully smaller. ADVANCED PDF FOR LIFETIME PRO - Set a Target for a supported PDF whose eligible raster image resources pass the calibrated safety rules. - Recompress only eligible image resources while keeping supported text, vectors, links, fonts, annotations, and static form fields as PDF content. - Validate every candidate locally before offering it. - Advanced PDF is best effort. It does not rasterize whole pages, run OCR, or guarantee an arbitrary Target size. REUSABLE LOCAL RESULTS - Download committed outputs under Downloads/Upload Rescue/. - Keep reusable results in clearable browser-managed local history. - Download again, delete one result, or clear all results. - Local history is a convenience, not a permanent backup. Chrome may remove local browser storage under quota or device pressure. FREE AND LIFETIME PRO - Free includes 10 committed local operations per local calendar day and up to 20 reusable results or 200 MiB. - Lifetime Pro is a one-time US$19 purchase with unlimited successful operations, Advanced PDF Targets for eligible documents, sequential JPG/PNG/WebP batch processing, saved presets, and up to 100 reusable results or 1 GiB. - Batch creates individual files in the Upload Rescue download folder. It does not create a ZIP. LIMITS Upload Rescue does not guarantee a Target for every file, support every HEIC variant or PDF, access website content, auto-fill upload fields, submit forms, or guarantee acceptance by another website. HEIC/HEIF is macOS-only in v0.5. Keep original copies of important files.
