Three steps. Under a minute.
The shortest path from a file on your desk to the result you needed. Drop, configure, download — and chain into the next operation without re-uploading.
- STEP · 01
Drop a folder
Browser-supported folder upload — drag the whole directory in. Mixed formats, mixed dimensions, all handled together.
- STEP · 02
Define a recipe
Chain operations in order: resize → convert → compress → strip EXIF → watermark → rename. Save recipes for repeat work; share with your team via the Cloud Pro preset library.
- STEP · 03
Run and download
The batch runs with a progress indicator. Results download as a single zip with the original folder structure preserved.
What makes FyDark's batch image optimizer actually different.
Drop a folder, define a recipe (resize → convert → compress → strip EXIF → watermark), and run it across the whole batch. Filenames preserved, output organized, processing parallelized. The end of one-image-at-a-time bulk work.
Free for daily work
No signup, no watermark, no daily caps. The free tier isn't a trial — it's the actual product.
Browser-first
Most operations stay on your device. We tell you exactly which ones don't, with a small label on every tool.
Cloud when it helps
AI cutouts and very large batches use a one-time encrypted server session. Daily resize, crop, compress, convert, effects, and EXIF cleanup stay local where possible.
Chains, not exports
The output of one operation is offered as input to the next. No re-uploading the same file four times in a row.
Common questions about batch image optimizer.
Privacy, format support, file-size, and the local-vs-cloud distinction — answered straight.
Free tier handles up to 25 images per batch; Cloud Pro extends to 1000+ per batch with server-side parallel processing for ~10× speedup. Same recipe, same output structure.
Tools that pair naturally with Batch Optimize.
Output of one operation becomes input to the next — no re-uploading, no exporting and re-importing. The chain works because the workspace stays open.
