How to convert images online

Add one or more supported images to the converter above. Choose WebP, AVIF, JPG, PNG or JPEG XL as the destination, select the quality mode and keep the original dimensions or set a maximum side. Riducly converts the batch and shows the resulting format and file size before you download each file or a ZIP. No account is required to begin.

Supported input and output formats

Riducly opens JPG and JPEG, PNG, WebP, AVIF, HEIC and HEIF, and JPEG XL images. It can create WebP, AVIF, JPG, PNG and JPEG XL output. HEIC and HEIF are input-only because the app does not include a HEIC encoder, so those photos must be converted to another format. Browser and device support can affect which codecs are available locally.

Choose quality and dimensions before converting

Lighter favors smaller lossy output, Balanced is designed for everyday use and High quality preserves more detail or uses lossless encoding where the destination supports it. Keep Original size when resolution must not change, or limit the longest side for web, email and previews. A different format is not guaranteed to be smaller: image content and settings determine the final byte size.

Batch conversion with clear privacy choices

Convert several images with the same settings and download the results separately or together. Desktop defaults to on-device processing. Mobile defaults to transient server processing to reduce memory pressure; server files are handled only in memory for the request and are not stored. The processing location can be changed before files are added, and the uploader displays the current guest or account limits.

Which image format should you choose?

Use JPG for broadly compatible photographs, PNG for lossless graphics and transparency, WebP for efficient modern web assets, AVIF when strong compression and current browser support are priorities, or JPEG XL for compatible specialist workflows. Converting rebuilds the output from decoded pixels: embedded metadata and animation are not preserved, and transparency survives only in destinations that support an alpha channel.

Frequently asked questions

Is the online image converter free?
Yes. Guest conversion works without registration. The uploader shows current limits, while a free account provides larger file and batch allowances and can enable parallel processing.
Can I convert HEIC images?
Yes. Riducly decodes HEIC and HEIF and converts them to WebP, AVIF, JPG, PNG or JPEG XL. It cannot create HEIC output.
Will transparent backgrounds be preserved?
Transparency can be retained in PNG, WebP and compatible AVIF output. JPG does not support transparency, so review transparent source images before choosing JPG.
Does conversion preserve metadata or animation?
No. Output is rebuilt from decoded still-image pixels, so embedded metadata, multi-image sequences and animation are not copied. Keep the source file when those elements matter.
Are converted images stored on a server?
No. Desktop defaults to local processing. When transient server processing is used, files remain in memory for the request and are not stored.
