Image Converter
Switch an image between JPG, PNG, and WebP — one file or a whole batch zipped together — with everything converted right in your browser, no account and no upload.
Image Converter is a browser-based image tool on ImgToolsBase. Switch an image between JPG, PNG, and WebP — one file or a whole batch zipped together — with everything converted right in your browser, no account and no upload. To use it, upload or drop your image and view the result directly in your browser — no signup and nothing to install.
How this tool works
Any format in, any out
Bring JPG, PNG, WebP, BMP, GIF, or HEIC and output JPG, PNG, WebP, or Same as input — the broad, all-purpose converter.
Batch to a ZIP
Convert one file or many; a single file downloads directly, while a batch is packaged as a ZIP with a per-file status list.
Quality & transparency
Quality applies to JPG and WebP (PNG is lossless); for JPG output you also choose the colour that fills any transparency.
Private by design
Everything runs in your browser; nothing is uploaded, and canvas re-encoding drops EXIF and other metadata.
Image Converter in your browser
Image Converter converts images in your browser and lets you choose the output format — JPG, PNG, WebP, or Same as input (which keeps JPG, PNG, or WebP and falls back to JPG for other formats). It is the broad, all-purpose converter — bring almost any image and output JPG, PNG, or WebP, one file or many.
Select multiple files to convert them all at once and download a ZIP, with a per-file status list that skips anything that is not an image and keeps going. For JPG output, pick the background color used to fill transparency; the quality slider applies to JPG and WebP only (PNG is lossless and ignores it). An optional target file size lets you aim for a size for JPG/WebP output, reported as under or over.
Image Converter processes everything in your browser — nothing is uploaded. Animated GIFs are exported as a single still frame — animation, timing, and frames are not preserved by this canvas tool. Re-encoding through the browser canvas removes EXIF and other metadata.
How to use Image Converter
- Upload one image, or select several, into Image Converter — click, press Enter, or drag files in.
- In Image Converter, choose the output format (JPG, PNG, WebP, or Same as input) and, for JPG, a background color; set the quality and an optional target size.
- Click Process and Image Converter converts — a single file downloads directly, while multiple files are packaged into a ZIP with a per-file status list.
- Review Image Converter’s result panel or per-file list — formats, dimensions, sizes, and how transparency was handled — then download.
Why use Image Converter
JPG, PNG, WebP, or Same as input — convert to what you need, or keep the original format for a metadata strip or size change.
Convert many images at once and download a single ZIP, with a per-file status list and skipped non-images noted.
Quality applies to JPG/WebP (PNG is lossless); JPG output flattens transparency to your chosen color, reported in the result.
Every conversion runs in your browser; nothing is uploaded.
Common uses for Image Converter
Drop a folder’s worth of images and get them all in one format as a ZIP.
Convert to JPG or WebP and use quality or a target size to make smaller files.
Use Same as input to strip metadata or approach a size without changing the format.
Convert from a phone, tablet, or computer browser with files staying local.
Frequently asked questions
Are my images uploaded to a server by Image Converter?
No. Image Converter converts every file in your browser using the HTML canvas, and nothing is sent to imgtoolsbase or any server.
Can Image Converter convert several files at once?
Yes. Select multiple images and Image Converter converts them all and downloads a ZIP, listing each file’s result and skipping any non-image files with a note.
Does the quality slider affect PNG output in Image Converter?
No. PNG is lossless, so most browsers ignore a quality value for PNG. In Image Converter the quality applies to JPG and WebP output; the result panel shows whether quality was used.
What does "Same as input" do in Image Converter?
In Image Converter, it keeps the original format when it is JPG, PNG, or WebP — useful when you only want to strip metadata, normalize, or approach a target size; other formats fall back to JPG, and the result panel says so.
What happens to transparency when Image Converter outputs JPG?
JPG cannot store transparency, so Image Converter fills transparent areas with the background color you choose; PNG and WebP output preserve transparency when the source has it.
Which formats can I convert with the Image Converter?
It reads the image formats your browser can decode (such as JPG, PNG, WebP, GIF, and BMP) and outputs JPG, PNG, or WebP, or keeps the same format. Anything the browser cannot decode is reported as skipped in batch mode.
