Batch Convert Images to SVG

Drop multiple images, pick an engine (VTracer for color or Potrace for black & white), and download a single ZIP containing every converted SVG. Ideal for vectorizing an icon set of 20 files fast.

Batch Convert
Up to 20 files × 25MB each. All files share one engine.

Every file in this batch uses the same engine.

About Batch Convert

When you have many images to convert — a 20-icon set, or product thumbnails to ship as SVG — Batch Convert fans N jobs out into the BullMQ queue. Each file is processed in parallel (concurrency 2), with real-time per-file progress tracking.

Once everything is done, the server packages the results with archiver into a single ZIP for download. Source images are deleted as soon as each worker finishes; the ZIP lives for 1 hour. Dozens of uploads and downloads collapsed into one.

  • Up to 20 files per batch
  • 25MB per file, no hard total limit
  • Parallel fan-out via BullMQ
  • Live per-file progress
  • Single ZIP download
  • Original filenames preserved (.svg)

How to batch convert images

  1. 1

    Drop multiple images

    Pick files or drop a folder. Duplicates are auto-numbered so the ZIP contains no name collisions.

  2. 2

    Pick a shared engine

    Color for full-color images. Mono for black-and-white logos. Mixed? Run two batches.

  3. 3

    Click Convert all

    N files → N jobs. You'll see per-file progress live.

  4. 4

    Wait for the batch to finish

    Large images take 3-30s, small logos under 5s. A 20-file batch typically takes 2-5 minutes.

  5. 5

    Download the ZIP

    Click download — the ZIP contains every .svg using the original filenames.

Batch Convert FAQ

What's the file limit?
20 files per upload. Need more? Split into multiple batches — there's no cap on how many batches you run (aside from the 30/hour/IP rate limit).
Is it parallel?
Worker concurrency is 2 (i5 dual-thread). 20 files are processed in 10 pairs. Still far faster than manual.
Does one failed file break the batch?
No. Failed jobs are marked failed; the rest continue. The ZIP only contains successful files.
Can I mix color and mono in one batch?
Currently there's one shared engine per batch. For mixed inputs, run two batches for best per-type quality.
