Frequently Asked Questions

Are my images uploaded to a server?

No. All batch processing happens entirely in your browser using local processing. Your files never leave your device and are never sent to any server.

How many images can I process at once?

You can process up to 50 images per batch, with a maximum file size of 10MB per image.

Can I resize and convert format at the same time?

Yes. You can apply format conversion, quality settings, and max width/height resizing all in a single batch run. All settings are applied to every image in the batch at once.

How does the rename feature work?

If you set a prefix, files will be renamed sequentially — for example, prefix-001.jpg, prefix-002.jpg, and so on. If no prefix is set, the original filenames are kept.

Is Tracelyx Batch free?

Yes, completely free. No account required, no usage limits, no watermarks.

How do I download the processed files?

After processing, click Download ZIP to get all converted images packed into a single ZIP archive. You can then extract the files wherever you need them.

How to Use Tracelyx Batch: A Complete Guide

Process Multiple Images in 4 Steps

Tracelyx Batch 4-step guide: add files, configure settings, process, download ZIP
  1. Add your images — Drop up to 50 JPEG, PNG, or WebP files into the upload area, or click to select them. Each file appears in the file list on the left.
  2. Configure settings — Set your output format (JPEG, PNG, WebP, or keep original), quality level, and optional max width/height for resizing. All settings apply to every image in the batch.
  3. Set a filename prefix (optional) — Enter a prefix to rename all files sequentially: prefix-001.jpg, prefix-002.jpg, and so on. Leave blank to keep original filenames.
  4. Process and download — Click Process batch. When complete, click Download ZIP to get all converted images in a single archive.

When to Use Batch Processing

Batch processing is the right choice whenever you need to apply the same operation to a set of files. Resizing an entire product catalog for a new storefront, converting a folder of PNG assets to WebP before deployment, stripping EXIF from every photo in a client delivery, or renaming a shoot's worth of files to a consistent naming scheme — any of these tasks that would take minutes of repetitive work per image can be done in a single batch run.

The key advantage over processing images one at a time is consistency. Every file in the batch gets exactly the same settings applied — the same quality level, the same output dimensions, the same format. There is no risk of accidentally exporting one file at a different quality or forgetting to strip EXIF from one image in the set.

File Renaming and Organization

Batch file renaming feature: prefix-001, prefix-002 sequential naming

The prefix rename feature is particularly useful for e-commerce and content workflows. Set a prefix like product-category-2026 and your files come out as product-category-2026-001.jpg, product-category-2026-002.jpg, and so on — ready to upload to a CMS, storefront, or file storage system without any manual renaming. The sequential number is zero-padded to three digits so files sort correctly in any file manager.

If you prefer to keep original filenames, simply leave the prefix field blank. The output format extension is updated automatically — a file named photo.png converted to WebP becomes photo.webp, with no manual renaming needed.

Batch Processing Without Uploading to Any Server

Processing large numbers of images through an online service creates a significant privacy exposure: every file in your batch passes through a remote server you don't control. For batches that include confidential client work, product images with unreleased designs, personal photos, or any assets you wouldn't want stored externally, this is a genuine risk.

Tracelyx Batch processes every image entirely inside your browser. The Canvas API reads each file locally, applies the format conversion and resizing, and packs the result into a ZIP — all without transmitting a single byte to a remote server. You can safely batch-process an entire client delivery, a confidential product catalog, or a personal photo archive without any files ever leaving your device.
