01 / WHAT
What is a bulk image converter?
Get newly encoded files
The converter retains pixel dimensions and creates downloadable files in your selected format. A ZIP collects all successful exports.
Conversion has tradeoffs
JPG loses transparency, lossy encoding may change detail, and original EXIF is not retained. Animation and HEIC inputs are not supported.
PRODUCT IMAGES, CONVERTEDActual tool outputs
Three PNG files converted to WebP at 85% quality. Conversion preserves pixel dimensions; compare the formats and actual file sizes.
02 / WHERE
Where can converted images be used?
Tools that require JPG
Prepare JPG copies for a workflow that cannot accept your source format, checking its other requirements separately.
Designs needing transparency
Use PNG or WebP to retain existing transparent pixels for layouts and overlays. Conversion does not remove an existing background.
Web asset libraries
Standardize mixed image formats before handing assets to a site editor or another member of your team.
03 / WHY
Why convert multiple images together?
One format for the handoff
Set a shared output format instead of choosing a separate export option for every file.
Choose the relevant controls
Use quality settings for JPG and WebP, or choose PNG when you want to avoid another lossy encoding step.
Work without an upload queue
The converter runs locally and is free without an account. Your originals stay available as separate files.
04 / WHEN
When should you convert images?
A destination rejects the format
If JPG, PNG or WebP is accepted by the destination, export a supported copy before trying again.
You receive mixed file types
Unify formats before a design handoff or publishing batch so the next step uses consistent file types.
You want to compare encoding options
Try different output formats and inspect both file size and visible quality before choosing which version to publish.
Frequently asked questions
Can I convert HEIC, GIF or SVG?
Not with this tool. Inputs are JPG, PNG and WebP. Animated images are unsupported.
Does PNG output restore lost quality?
No. Converting a lossy image to PNG cannot recover information already lost in the source.
Does conversion resize my image?
No. It preserves pixel dimensions. Use Resize to change width or percentage and Compress for a maximum KB target.
Why did my transparent image get a white background?
JPG has no transparency support. Choose PNG or WebP if you need to retain transparent regions.
How many images can I convert?
Up to 30 per batch, 20 MB each. Inputs and outputs are limited to 32 megapixels, with a 16,384 px maximum output side; browser capabilities can impose additional limits.
