How to Convert Images in Bulk Online for Free
You have a folder of 25 WebP screenshots and you need them all as JPG. Or you received a batch of TIFF files from a photographer and need them as PNG for your website. A batch image converter online lets you process all of them at once instead of uploading them individually.
How Batch Conversion Works
Batch conversion is straightforward. Instead of uploading one file, selecting a format, downloading, and repeating, you upload all your files at once. The tool converts them all to your chosen format and gives you a single ZIP download.
On LoveConverts, the process is:
- Go to the image converter (the homepage) or the batch convert tool.
- Upload your files. Drag and drop up to 30 files, or click to browse. You can also add files incrementally.
- Select the target format. Pick from JPG, PNG, WebP, AVIF, GIF, or TIFF.
- Click Convert. All files are processed server-side. A progress bar shows which file is being converted.
- Download the ZIP. One click gets you all converted files in a single archive.
Which Batch Converter to Use (And Why Most Are Bad)
Most online batch converters have annoying limitations. Some cap you at 5 files unless you pay. Others add watermarks. A few make you wait 30 seconds between conversions to encourage upgrading.
LoveConverts processes up to 30 files at once with no signup, no watermarks, and no artificial delays. The conversion happens server-side using Sharp (the same library used by companies like Netflix and Shopify for image processing), so it is fast and produces high-quality output.
Supported Formats and Conversions
The batch converter supports all common image formats:
- Input formats: JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO
- Output formats: JPG, PNG, WebP, AVIF, GIF
This means you can do any combination: WebP to JPG, PNG to WebP, TIFF to PNG, BMP to JPG, and so on. All in one batch.
When Batch Conversion Saves Serious Time
A few real scenarios where batch conversion pays off:
- Website migration: Moving from one CMS to another and need all images in a different format.
- Client deliverables: A client sent you files in TIFF but you need JPG for the website.
- Screenshot documentation: Your screenshot tool saves as PNG, but your documentation platform prefers WebP.
- Photo batches: Processing a set of photos from a shoot before uploading to social media.
In all these cases, manual one-by-one conversion would take 15-30 minutes. Batch conversion takes under a minute.
Combine Batch Converting with Compression
Here is a workflow that saves both time and file size: first batch convert your images to the target format, then batch compress them using the image compressor. Both tools accept up to 30 files at once.
For example: convert 20 TIFF photos to JPG (reduces file size from ~30MB each to ~3MB each), then compress the JPGs (reduces from ~3MB to ~500KB each). Your 600MB of TIFFs become 10MB of optimized JPGs, ready for web use.
