Bulk Image Resize, Compress and Convert (Free, In-Browser)
Batch resize, compress, and convert dozens of images at once — all in your browser, no uploads. Download every result as a single ZIP.
One photo is easy; 200 photos is a chore. The Bulk tool at resizeimagesfree resizes, compresses, and converts an entire folder of images in your browser — no server upload, no queue, no per-file cost.
What bulk mode can do
- Resize every image to the same max width or height while keeping aspect ratios.
- Convert JPG, PNG, and WebP to any of the other formats in one pass.
- Compress to a target quality across the whole batch.
- Download all results in one click.
Step-by-step
- Open the Bulk tool.
- Drop a folder or multi-select files.
- Pick target dimensions, format, and quality.
- Click Process. Each row shows status as the browser works through the batch.
- Click Download all when done.
Performance tips
- Chromium browsers process batches faster than Safari — a laptop can handle 200 JPGs in about a minute.
- For very large batches, close other heavy tabs so the browser can use more RAM.
- Convert-to-WebP is the biggest single win — expect 25–35% smaller files at the same visual quality.
