Your images will appear here.
Everything runs locally — nothing is uploaded.
Drag a whole folder, browse files or paste a screenshot. Up to 2,000 images per batch, no account needed.
Choose WebP, JPG, PNG or AVIF, set a quality level or target file size, and resize to the exact dimensions you need.
Get every converted image in one tidy ZIP — original names kept, or renamed with a clean numbered pattern.
Most online converters upload your photos to a server, process them there and send them back. That means your images travel over the internet, sit in someone else's queue and may be kept for hours or longer. BulkMedia works differently: your browser already contains a complete image engine. We use it directly, so a 2,000-image batch never leaves your laptop.
Images are usually the heaviest part of a web page. Google's Core Web Vitals measure Largest Contentful Paint and Cumulative Layout Shift, both of which are dominated by image weight. Converting photos to WebP and resizing them to the size they are actually displayed at routinely cuts page weight by 60–80% — no code changes required.
Product catalogues, blog archives, real-estate listings and school photo projects all have the same problem: hundreds of images that need the same treatment. Bulk conversion with a target file size means you can say "make everything under 100 KB" once and get a ZIP back, instead of adjusting a slider 300 times.
Yes — completely free, with no signup, no watermark and no daily limit. The tool is supported by advertising on this page, which is why the converter itself can stay free.
No. Images are read and re-encoded by your own browser using the Canvas API and Web Workers. Nothing is transmitted. You can even disconnect from the internet after the page loads.
At the same visual quality, WebP files are typically 25–35% smaller than JPEG and far smaller than PNG. All modern browsers support WebP, and WordPress has supported it since version 5.8.
The practical limit is your device's memory, not our servers. Batches of 500–1,000 images work comfortably on a modern laptop; the tool processes them in parallel with 2–4 background workers.
HEIC is a proprietary Apple format. Safari and iOS decode it natively, but Chrome and Firefox cannot. Use Safari, or export the photos as JPG from the iPhone share sheet first — the tool will flag HEIC files clearly instead of failing silently.
Yes. Switch to "Target file size" mode and enter a value such as 100 KB. The converter automatically searches for the best quality and, if needed, reduces dimensions to hit your limit.
Yes. The interface is fully responsive and photos can be added straight from your camera roll. Large batches are best done on desktop, but normal phone photos convert quickly.
