Frequently Asked Questions
- How do I batch or bulk compress images?
- Select multiple images using the file picker or drag-and-drop, choose your compression quality and output format, wait for the batch queue to finish, then click Download ZIP to save every processed file at once. Bulk image compression uses the same workflow — upload many photos, apply one set of settings, and download everything together.
- What is bulk image compression?
- Bulk image compression means reducing file size for many photos in one session instead of one at a time. Our free bulk image compressor processes up to 50 JPG, PNG, WebP, AVIF, or HEIC images with the same settings and bundles results into a single ZIP download.
- How many images can I batch or bulk compress at once?
- You can bulk compress up to 50 images per batch. Each file can be up to 50 MB. Processing runs locally in parallel so the UI stays responsive during bulk uploads.
- Can I bulk download all compressed images as a ZIP?
- Yes. When bulk processing completes, use the Download ZIP button to bundle every finished image into one archive with sanitized filenames — ideal for bulk photo compression workflows.
- Are bulk or batch uploads sent to a server?
- No. Bulk and batch compression run entirely in your browser. Your images never leave your device — whether you compress one file or an entire bulk upload.
