Convert JPG and WebP photos in your browser with quality and resize controls, then compare bytes, texture, gradients, and destination support.
What this page is for
JPG and WebP are both practical photo-delivery formats. WebP can be efficient for modern sites, while JPG remains broadly accepted by editors and publishing systems.
Do not expect conversion to restore detail already lost to compression.
Check fine textures and gradients after lowering quality.
JPG and WebP are common delivery formats for photographs. This page helps create an efficient WebP for a modern site or a conventional JPG for a service that does not accept WebP. The conversion changes encoding, not the underlying photographic detail.
How to convert your file
1Add the photograph and choose JPG or WebP as the output.
2Keep the original size unless the destination has a known pixel limit.
3Select a quality level, convert, and view the result at 100% zoom.
4Check hair, foliage, text, and smooth gradients before deciding that the file-size saving is worthwhile.
Export settings
Quality
Use the previewed result, not the percentage alone. Different encoders and different images do not produce identical results at the same number.
Maximum size
A 1600-pixel delivery file can be more appropriate than a full camera-resolution image when the page never displays it larger.
Smoothing
High smoothing is normally appropriate for photographs. Nearest-neighbour resampling is intended for hard-edged pixel art.
Colour changes
Disable enhancements for a format-only comparison so colour and contrast do not confuse the result.
Like-for-like check
Keep pixel dimensions equal, record the byte size of each output, and inspect both at 100% for ringing around edges, blockiness in fine texture, and banding in gradients. Recheck the winner at its final display size.
Before you download
Repeated conversion between two lossy formats can accumulate compression artefacts.
JPG cannot preserve transparency and this page is intended for still images.
Colour may vary slightly between software because browsers and editors can handle colour profiles differently.
Questions and answers
Can conversion restore a blurry photograph?
No. Sharpening can change edge contrast, but it cannot reconstruct detail that the source never contained.
Which format is safer for compatibility?
JPG remains the conservative choice for older tools. WebP is usually appropriate for current web browsers.
Should I convert an already compressed image twice?
Avoid unnecessary lossy generations. Work from the best available source and create the delivery format once.
