How your files are processed
Files are uploaded and processed on our servers, then made available for download.
What this tool does
Resize image sets new pixel width and height caps server-side while keeping aspect ratio.
Shrinks DSLR or phone masters before CMS, email, or gallery uploads.
- Raster in, raster out — Resize image reads common JPEG, PNG, and WebP sources and writes the file type the form advertises—alpha PNG, recompressed JPEG, or plain TXT for OCR.
- Server-side models — Matting, geometry, and OCR use tuned backends instead of single-threaded in-tab scripts on huge files.
- Still too big? — After editing, run the matching compressor profile if email or mobile data still rejects the bytes.
How to use Resize image?
- Upload — choose the file (or files, if the tool allows multiple) in the supported formats listed on this page.
- Configure — set options such as dimensions, watermark text, or OCR language using the fields above.
- Run and download — submit the job, wait for processing, then download your result before the automatic expiry window.
Why use Resize image?
Resize image exists for gallery plugins and attachment ceilings—set max edge length once and download a lighter JPEG or WebP.
Good when editors refuse 15 MB hero shots but you still need crisp detail at published sizes.
Common uses for Resize image
- Shrink 24 MP holiday shots before blogging on metered hotel Wi‑Fi.
- Produce 1920 px previews for Figma comments without mailing RAW files.
- Drop texture PNGs under Unity or Unreal import caps.
- Drop results into Slack threads—the /tools/resize-image resize image flow matches Windows and macOS Chrome.
Output quality tips for Resize image
Downscaling usually sharpens perceived detail; upscaling cannot invent real texture.
For enlargements, start from the highest-quality source you have. JPEG generations may show compression if you re-save lossy formats repeatedly.
Resize image: /utilities vs server image tool
Browser utilities (/utilities)
Color pickers, EXIF viewers, and text helpers run as JavaScript in your tab. Bitmaps you open there never upload to FileConvert.
This image tool (upload)
Resize image downscales width and height caps on workers so 24–45 MP frames finish without wedging Chrome.
Resize GIFs or icons locally if they are kilobytes. Open Resize image when DSLR exports must shrink before WordPress or Gmail accept them.
Troubleshooting
- Upload fails or stalls: refresh the page, try another browser, or pause strict blockers for this site.
- Extension mismatch: compare your filename with the types named on this page above the upload control.
- Unexpected output: verify time ranges, pixel boxes, OCR languages, or watermark opacity, then rerun once.
- Large file limitations: Resize image jobs can exceed upload or processing limits; try a smaller image first.
- Viewer differences: Safari, Chrome, and design apps tint PNG or WebP differently—open the download in the final app before publishing.
