Workflow
How to batch process images for the web
Use one local workflow to resize a group of website images, choose a practical format, check real file sizes, and export predictable names before uploading.

Add the source images
Open Batch Image Processor and choose JPG, PNG, or WebP images. Folder selection is a browser enhancement; multi-file selection and ZIP download remain the baseline path.
Batch Image ProcessorResize without stretching
Use Longest edge or a locked pixel box. Each image is calculated from its own dimensions, so portrait and landscape files keep their proportions.
Batch Image ProcessorChoose the final format
Use WebP when the destination accepts it, JPG for broad photo compatibility, and PNG for transparency or crisp graphic edges. Do not choose a format just because it is familiar.
Image ConverterRun a real sample
Review one exported image before processing the full batch. Check dimensions, transparency, watermark placement, and the actual byte size rather than an estimate.
Batch Image ProcessorExport and inspect
Process the remaining files, retry only failures, then download a ZIP or save successful results to a newly chosen folder. Keep the source folder unchanged.
Batch Image ProcessorBefore uploading
- The output format matches the site or CMS
- Portrait and landscape images keep their proportions
- The largest files meet the actual upload limit
- Names are stable and do not overwrite source files
- Visible private details and metadata boundaries have been reviewed
- The original files remain in a separate folder
Does this workflow upload images?
No. Pixlery inspects and processes supported images in your browser. The batch workflow does not send image data to a server.
Should I compress before resizing?
In this workflow, resize and other pixel operations happen before the final encode. That avoids repeatedly decoding and re-encoding intermediate files.
Can I target an exact file size?
JPG and WebP can use a bounded quality search from the same final Canvas. Exact size is not guaranteed; the tool reports when a limit cannot be reached.
Should I preserve EXIF?
Treat the exported web set as a delivery copy. Canvas output is a new image and Pixlery does not claim to preserve EXIF, GPS, ICC, or DPI metadata.
