About this tool
Resize supported JPG files with independent dimensions or locked proportions.
- Supported input
- JPG
- Output format
- JPG
- Batch size
- Up to 5 files; format and combined limits below still apply.
How it works
- Add JPG files in Input. Review each thumbnail and its validation status.
- Select a thumbnail to edit that image’s dimensions. Lock its proportions or apply one width to the selected batch.
- Create the selected files. Compare original and result, then download an individual file or ZIP. Changing settings marks older results out of date.
Supported files and limits
Up to 5 files, 10 MiB each and 25 MiB combined. Each image must fit within 8192 pixels per side and 20 million pixels; a batch is limited to 40 million input pixels. Output is limited to 20 MiB per file and 50 MiB combined. One isolated image job runs at a time, with a 30-second timeout and cancellation.
A practical example
For a 1200 by 800 photograph needed at 600 pixels wide, lock proportions and set width to 600. The target height becomes 400.
Troubleshooting this tool
The resized file is a new JPG export. Enlarging it interpolates pixels and does not restore missing detail; inspect small lettering and fine textures after resizing.
JPG input supports 8-bit baseline/progressive RGB or grayscale. EXIF/ICC/multi-picture metadata and CMYK are currently rejected, so orientation and colour profiles are not silently discarded. Export an unprofiled copy from your image editor if needed.
Check the actual export
JPG export is re-encoded at the selected quality. Enlarging does not recover real detail. Inspect downloaded dimensions, transparency and fine edges before replacing an original. Browser encoders differ; a quality setting is not a universal fidelity score, and file size may increase.
Files stay in your browser
No file bytes are uploaded. Ordinary work stays in memory. Choosing a “Continue” action saves that result in this browser for up to 30 minutes, so another compatible working tool can use the actual output. Saved workflows are limited to 50 MiB and 20 files; clear them in Output. Expired entries are removed on later tool visits. Clearing references is not a secure-erasure promise.
If a file fails
Check its actual format and the restrictions above. Renaming a file does not convert it. A failed file does not erase successful batch results. If processing times out, cancel and try fewer or smaller files. A current browser with worker canvas support is required.
Before you use the download
- Open the download and verify its width and height against the settings you chose.
- Look for stretched proportions or softened detail, especially if you enlarged the source.
