About this tool

About Image Converter

Choose this page when the main question is which image format to deliver. Convert a supported photo, screenshot or graphic to JPG, PNG, WebP, AVIF, GIF or BMP without changing the source file.

Choose by transparency and destination

For a photo upload that requires JPG, use JPG and inspect fine detail after lossy encoding. For a logo that needs a transparent background, consider PNG or WebP instead: JPG has no alpha channel and this converter fills transparent regions with white. AVIF and WebP may suit web delivery when the destination supports them; test actual output size rather than assuming a newer format is always smaller.

GIF output here is a still image, not an animation maker. Animated GIF input is also processed as a single frame. BMP may be needed by legacy software, but often produces a much larger file.

Convert a representative sample first

  1. Add one supported image and select the destination format.
  2. Adjust quality where the selected encoder uses it; PNG does not use a lossy quality setting.
  3. Start conversion and download the result.
  4. Check its type, pixel dimensions, transparency, orientation and visual detail.
  5. Open it in the receiving app before converting the rest of a collection.

For example, a transparent product logo converted to JPG needs its new white background checked against the destination page. A photo converted from JPG to PNG will not regain detail lost in the original JPG.

Format conversion is not resizing or cropping

On this page the converter keeps the decoded dimensions; it does not expose width, height or crop controls. Use Image Resizer for dimensions, Image Cropper for composition, or the convert, resize and compress workflow when those steps should run together.

One image or a folder?

This converter also accepts multiple images. Batch Image Converter uses the same underlying component and limits; its instructions focus on consistent settings, failed items and checking a downloaded collection. There is no separate batch-only quality engine.

Both entries accept up to 100 images, with a 30 MB per-file and 500 MB combined limit. Processing is sequential; failed files are listed while other items can continue. Only successful outputs are included in the download. A successful result does not guarantee that camera metadata, color profiles or animation have been retained.

Keep the original

Processing compatible inputs stays on the device, although loading the application requires a connection. Save the result before leaving and keep the original until the destination has accepted the converted copy.

Frequently asked questions

Image Converter FAQ

What does Image Converter change?

It decodes a supported image and re-encodes it as JPG, PNG, WebP, AVIF, GIF or BMP. This page changes format; use the separate resizer or cropper to change dimensions or composition.

Can this page also convert a batch?

Yes. Image Converter and Batch Image Converter use the same converter and accept multiple files. The batch page explains queue preparation and checking a folder of results; it does not unlock a different encoder.

Which format keeps a transparent background?

PNG and WebP can preserve transparency. JPG uses an opaque background; this converter fills transparent areas with white. Check edges after conversion.

Will GIF output preserve an animation?

No. This image converter produces a still image. Animated GIF input is processed as one frame; keep the original when animation matters.

What are the file limits?

Up to 100 images, 30 MB per image and 500 MB combined. Large pixel dimensions may still exceed available device memory.

Are images uploaded?

Compatible image processing runs in the browser. The page and processing modules still need network requests to load, but normal conversion does not send the source image to zer.ai.
