Overview
What Is an Image Converter?
An image converter changes a picture from one file format to another so it is easier to open, share, publish, or upload. The imglab Image Converter accepts multiple images in one batch, including HEIC and HEIF photos, then creates JPG, PNG, or WebP copies. You can keep the original dimensions or set a maximum edge to reduce oversized images while converting. Processing takes place on your device, and the finished files are available as individual downloads or one convenient ZIP.
Step by Step
How to Convert Images Online
- 01
Add Your Images
Drag several files into the upload area or choose images from your device. Review each preview, format, dimension, and file size.
- 02
Choose Conversion Settings
Pick JPG, PNG, or WebP. Optionally enable resizing and enter the maximum width or height you want for every image.
- 03
Convert the Batch
Select Convert Images and follow the progress bar while the files are processed one at a time in your browser.
- 04
Download Your Results
Save any converted image individually. If several results are ready, download the entire batch together as a ZIP file.
Key Use Cases
What You Can Do with Image Converter
Prepare Images for Websites
Turn JPG or PNG assets into WebP for modern websites, and use the maximum-edge option to avoid publishing source images that are much larger than their intended display size.
Preserve Transparent Graphics
Choose PNG when logos, icons, interface graphics, and product cutouts need a transparent background. If you select JPG instead, transparent areas are placed on a white background for predictable viewing.
Standardize a Mixed Image Folder
Add images received in different supported formats and export them all as one consistent file type. The result list provides the new name, dimensions, and size before you download anything.
Advantages
Why Use Image Converter on imglab?
Batch Conversion in One Workflow
Select multiple images, apply one output format and resize setting, then convert the complete group without repeating the same steps for every file.
Local Image Processing
The images you select are processed locally in your browser. They are not uploaded to or stored on an imglab server during this conversion workflow.
Clear Results Before Download
Check every output filename, pixel dimension, and file size in a compact result list. Download one file immediately or collect multiple results in a ZIP.
Conversion and Resizing Together
Set a maximum edge when large images also need smaller dimensions. Images keep their proportions, and sources already within the limit are not enlarged.
Tips
Tips for Better Image Conversion Results
Choose JPG for photographs that need broad compatibility, PNG for graphics that require transparency, and WebP for compact web-ready images. Start from the best source available because converting a low-quality image cannot restore missing detail. When resizing a mixed batch, choose a maximum edge that suits the largest place the images will appear. Animated source formats are converted to a still image, and available memory can affect very large files or batches.
Image Converter FAQ
Which image formats can I upload?
You can upload common formats your browser can decode, including JPG, PNG, WebP, AVIF, GIF, BMP, and SVG, plus HEIC and HEIF files. Browser and device capabilities can vary, so an unusual or damaged file may still fail to open.
Which output formats are available?
The converter creates JPG, PNG, or WebP files. JPG is widely compatible and works well for photos, PNG supports transparency, and WebP is a useful compact format for modern websites and apps.
Can I convert several images at once?
Yes. Add multiple images, choose one set of conversion options, and process the complete batch. Each result has its own download button, while Download All creates a ZIP when more than one result is available.
Does resizing stretch or enlarge my images?
No. Maximum-edge resizing keeps the original proportions. The longest side is reduced to the limit you enter, while the other side is calculated automatically. Smaller images remain at their original dimensions.
Are my images uploaded or stored?
No. This converter processes selected images on your device and does not upload them to an imglab server. Closing or refreshing the page clears the active workflow, while files you downloaded remain on your device.
What happens to transparency and animation?
PNG and WebP can retain transparent areas. JPG does not support transparency, so those areas receive a white background. Animated images are exported as a still image rather than a new animation.
